GENERAL DESCRIPTION
APPLICATIONS
ALD114804A/ALD114804/ALD114904A/ALD114904 are high precision monolithic
quad/dual depletion mode N-Channel MOSFETs matched at the factory using
ALD’s proven EPAD® CMOS technology. These devices are intended for low
voltage, small signal applications. They are excellent functional replacements for
normally-closed relay applications, as they are normally on (conducting) without
any power applied, but could be turned off or modulated when system power
supply is turned on. These MOSFETS have the unique characteristics of, when
the gate is grounded, operating in the resistance mode for low drain voltage levels and in the current source mode for higher voltage levels and providing a constant drain current.

circuits

digital circuits

ALD114804A/ALD114804/ALD114904A/ALD114904 MOSFETs are designed for
exceptional device electrical characteristics matching. As these devices are on
the same monolithic chip, they also exhibit excellent temperature tracking characteristics. They are versatile as design components for a broad range of analog
applications, such as basic building blocks for current sources, differential amplifier input stages, transmission gates, and multiplexer applications. Besides
matched pair electrical characteristics, each individual MOSFET also exhibits well
controlled parameters, enabling the user to depend on tight design limits corresponding to well matched characteristics.
These depletion mode devices are built for minimum offset voltage and differential thermal response, and they are suitable for switching and amplifying applications in single supply (0.4V to +5V) or dual supply (+/-0.4V to +/-5V) systems
where low input bias current, low input capacitance and fast switching speed are
desired. These devices exhibit well controlled turn-off and sub-threshold
charactersitics and therefore can be used in designs that depend on sub-threshold characteristics.
The ALD114804A/ALD114804/ALD114904A/ALD114904 are suitable for use in
precision applications which require very high current gain, beta, such as current
mirrors and current sources. A sample calculation of the DC current gain at a drain
current of 3mA and input leakage current of 30pA at 25°C is 3mA/30pA =
100,000,000. For most applications, connect the V+ pin to the most positive voltage and the V- and IC pins to the most negative voltage in the system. All other
pins must have voltages within these voltage limits at all times.

PERFORMANCE CHARACTERISTICS OF EPAD®
PRECISION MATCHED PAIR MOSFET FAMILY
ALD1108xx/ALD1109xx/ALD1148xx/ALD1149xx are monolithic
quad/dual N-Channel MOSFETs matched at the factory using ALD’s
proven EPAD® CMOS technology. These devices are intended for
low voltage, small signal applications.
ALD’s Electrically Programmable Analog Device (EPAD) technology provides a family of matched transistors with a range of precision threshold values. All members of this family are designed and
actively programmed for exceptional matching of device electrical
characteristics. Threshold values range from -3.50V Depletion to
+3.50V Enhancement devices, including standard products specified at -3.50V, -1.30V, -0.40V, +0.00V, +0.20V, +0.40V, +0.80V,
+1.40V, and +3.30V. ALD can also provide any customer desired
value between -3.50V and +3.50V. For all these devices, even the
depletion and zero threshold transistors, ALD EPAD technology
enables the same well controlled turn-off, subthreshold, and low
leakage characteristics as standard enhancement mode MOSFETs.
With the design and active programming, even units from different
batches and different dates of manufacture have well matched characteristics. As these devices are on the same monolithic chip, they
also exhibit excellent tempco tracking.
This EPAD MOSFET Array product family (EPAD MOSFET) is available in the three separate categories, each providing a distinctly
different set of electrical specifications and characteristics. The first
category is the ALD110800/ALD110900 Zero-Threshold™ mode
EPAD MOSFETs. The second category is the ALD1108xx/
ALD1109xx enhancement mode EPAD MOSFETs. The third category is the ALD1148xx/ALD1149xx depletion mode EPAD
MOSFETs. (The suffix “xx” denotes threshold voltage in 0.1V steps,
for example, xx = 08 denotes 0.80V).
The ALD110800/ALD110900 (quad/dual) are EPAD MOSFETs in
which the individual threshold voltage of each MOSFET is fixed at
zero. The threshold voltage is defined as IDS = 1µA @ VDS = 0.1V
when the gate voltage VGS = 0.00V. Zero threshold devices operate in the enhancement region when operated above threshold voltage and current level (VGS > 0.00V and IDS > 1µA) and subthreshold region when operated at or below threshold voltage and current level (VGS <= 0.00V and IDS < 1µA). This device, along with
other very low threshold voltage members of the product family,
constitute a class of EPAD MOSFETs that enable ultra low supply
voltage operation and nanopower type of circuit designs, applicable
in either analog or digital circuits.
The ALD1108xx/ALD1109xx (quad/dual) product family features
precision matched enhancement mode EPAD MOSFET devices,
which require a positive bias voltage to turn on. Precision threshold
values such as +1.40V, +0.80V, +0.20V are offered. No conductive
channel exists between the source and drain at zero applied gate
voltage for these devices, except that the +0.20V version has a
subthreshold current at about 20nA.
The ALD1148xx/ALD1149xx (quad/dual) features depletion mode
EPAD MOSFETs, which are normally-on devices when the gate
bias voltage is at zero volts. The depletion mode threshold voltage
is at a negative voltage level at which the EPAD MOSFET turns off.
Without a supply voltage and/or with VGS = 0.0V the EPAD MOSFET
device is already turned on and exhibits a defined and controlled
on-resistance between the source and drain terminals.
The ALD1148xx/ALD1149xx depletion mode EPAD MOSFETs are
different from most other types of depletion mode MOSFETs and
certain types of JFETs in that they do not exhibit high gate leakage
currents and channel/junction leakage currents. When negative
ALD114804A/ALD114804/
ALD114904A/ALD114904, Vers. 2.3
signal voltages are applied to the gate terminal, the designer/user
can depend on the EPAD MOSFET device to be controlled, modulated and turned off precisely. The device can be modulated and
turned-off under the control of the gate voltage in the same manner
as the enhancement mode EPAD MOSFET and the same device
equations apply.
EPAD MOSFETs are ideal for minimum offset voltage and differential thermal response, and they are used for switching and amplifying applications in low voltage (1V to 10V or +/-0.5V to +/-5V) or
ultra low voltage (less than 1V or +/-0.5V) systems. They feature
low input bias current (less than 30pA max.), ultra low power
(microWatt) or Nanopower (power measured in nanoWatt) operation, low input capacitance and fast switching speed. These devices can be used where a combination of these characteristics
are desired.
KEY APPLICATION ENVIRONMENT
EPAD MOSFET Array products are for circuit applications in one or
more of the following operating environments:
* Low voltage: 1V to 10V or +/-0.5V to +/-5V
* Ultra low voltage: less than 1V or +/-0.5V
* Low power: voltage x current = power measured in microwatt
* Nanopower: voltage x current = power measured in nanowatt
* Precision matching and tracking of two or more MOSFETs
ELECTRICAL CHARACTERISTICS
The turn-on and turn-off electrical characteristics of the EPAD
MOSFET products are shown in the Drain-Source On Current vs
Drain-Source On Voltage and Drain-Source On Current vs GateSource Voltage graphs. Each graph shows the Drain-Source On
Current versus Drain-Source On Voltage characteristics as a function of Gate-Source voltage in a different operating region under
different bias conditions. As the threshold voltage is tightly specified, the Drain-Source On Current at a given gate input voltage is
better controlled and more predictable when compared to many
other types of MOSFETs.
EPAD MOSFETs behave similarly to a standard MOSFET, therefore classic equations for a n-channel MOSFET applies to EPAD
MOSFET as well. The Drain current in the linear region (VDS <
VGS - VGS(th)) is given by:
IDS = u . COX . W/L . [VGS - VGS(th) - VDS/2] . VDS
where:
u = Mobility
COX = Capacitance / unit area of Gate electrode
VGS = Gate to Source voltage
VGS(th) = Turn-on threshold voltage
VDS = Drain to Source voltage
W = Channel width
L = Channel length
In this region of operation the IDS value is proportional to VDS value
and the device can be used as a gate-voltage controlled resistor.
For higher values of VDS where VDS >= VGS - VGS(th), the saturation current IDS is now given by (approx.):
IDS = u . COX . W/L . [VGS - VGS(th)]2

PERFORMANCE CHARACTERISTICS OF EPAD®
PRECISION MATCHED PAIR MOSFET FAMILY (cont.)
SUB-THRESHOLD REGION OF OPERATION
ZERO TEMPERATURE COEFFICIENT (ZTC) OPERATION
Low voltage systems, namely those operating at 5V, 3.3V or less,
typically require MOSFETs that have threshold voltage of 1V or
less. The threshold, or turn-on, voltage of the MOSFET is a voltage
below which the MOSFET conduction channel rapidly turns off. For
analog designs, this threshold voltage directly affects the operating
signal voltage range and the operating bias current levels.
For an EPAD MOSFET in this product family, there exist operating
points where the various factors that cause the current to increase
as a function of temperature balance out those that cause the current to decrease, thereby canceling each other, and resulting in net
temperature coefficient of near zero. One of these temperature
stable operating points is obtained by a ZTC voltage bias condition, which is 0.55V above a threshold voltage when VGS = VDS,
resulting in a temperature stable current level of about 68µA. For
other ZTC operating points, see ZTC characteristics.
At or below threshold voltage, an EPAD MOSFET exhibits a turnoff characteristic in an operating region called the subthreshold region. This is when the EPAD MOSFET conduction channel rapidly
turns off as a function of decreasing applied gate voltage. The conduction channel induced by the gate voltage on the gate electrode
decreases exponentially and causes the drain current to decrease
exponentially. However, the conduction channel does not shut off
abruptly with decreasing gate voltage. Rather, it decreases at a
fixed rate of approximately 116mV per decade of drain current decrease. Thus, if the threshold voltage is +0.20V, for example, the
drain current is 1µA at VGS = +0.20V. At VGS = +0.09V, the drain
current would decrease to 0.1µA. Extrapolating from this, the drain
current is 0.01µA (10nA) at VGS = -0.03V, 1nA at VGS = -0.14V,
and so forth. This subthreshold characteristic extends all the way
down to current levels below 1nA and is limited by other currents
such as junction leakage currents.
PERFORMANCE CHARACTERISTICS
Performance characteristics of the EPAD MOSFET product family
are shown in the following graphs. In general, the threshold voltage
shift for each member of the product family causes other affected
electrical characteristics to shift with an equivalent linear shift in
VGS(th) bias voltage. This linear shift in VGS causes the subthreshold I-V curves to shift linearly as well. Accordingly, the subthreshold
operating current can be determined by calculating the gate voltage drop relative to its threshold voltage, VGS(th).
RDS(ON) AT VGS = GROUND
At a drain current to be declared “zero current” by the user, the
VGS voltage at that zero current can now be estimated. Note that
using the above example, with VGS(th) = +0.20V, the drain current
still hovers around 20nA when the gate is at zero volts, or ground.
LOW POWER AND NANOPOWER
When supply voltages decrease, the power consumption of a given
load resistor decreases as the square of the supply voltage. So
one of the benefits in reducing supply voltage is to reduce power
consumption. While decreasing power supply voltages and power
consumption go hand-in-hand with decreasing useful AC bandwidth
and at the same time increases noise effects in the circuit, a circuit
designer can make the necessary tradeoffs and adjustments in any
given circuit design and bias the circuit accordingly.
With EPAD MOSFETs, a circuit that performs a specific function
can be designed so that power consumption can be minimized. In
some cases, these circuits operate in low power mode where the
power consumed is measure in micro-watts. In other cases, power
dissipation can be reduced to the nano-watt region and still provide
a useful and controlled circuit function operation.
ALD114804A/ALD114804/
ALD114904A/ALD114904, Vers. 2.3
Several of the EPAD MOSFETs produce a fixed resistance when
their gate is grounded. For ALD110800, the drain current is 1µA at
VDS = 0.1V and VGS = 0.0V. Thus, just by grounding the gate of
the ALD110800, a resistor with RDS(ON) = ~100KΩ is produced.
When an ALD114804 gate is grounded, the drain current IDS =
18.5µA @ VDS = 0.1V, producing RDS(ON) = 5.4KΩ. Similarly,
ALD114813 and ALD114835 produce drain currents of 77µA and
185µA, respectively, at VGS = 0.0V, and RDS(ON) values of 1.3KΩ
and 540Ω, respectively.
MATCHING CHARACTERISTICS
A key benefit of using a matched pair EPAD MOSFET is to maintain temperature tracking. In general, for EPAD MOSFET matched
pair devices, one device of the matched pair has gate leakage currents, junction temperature effects, and drain current temperature
coefficient as a function of bias voltage that cancel out similar effects of the other device, resulting in a temperature stable circuit.
As mentioned earlier, this temperature stability can be further enhanced by biasing the matched-pairs at Zero Tempco (ZTC) point,
even though that could require special circuit configuration and
power consumption design consideration.
