200MHz Slew Enhanced VFA
Features
The EL5100, EL5101, and EL5300 represent high-speed
voltage feedback amplifiers based on the current feedback
amplifier architecture. This gives the typical high slew rate
benefits of a CFA family along with the stability and ease of
use associated with the VFA type architecture. This family is
available in single, dual, and triple versions, with 200MHz,
400MHz, and 700MHz versions. This family operates on
single 5V or ±5V supplies from minimum supply current. The
EL5100 and EL5300 also feature an output enable function,
which can be used to put the output in to a high-impedance
mode. This enables the outputs of multiple amplifiers to be
tied together for use in multiplexing applications.

Applications
NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020C.

FIGURE 30. VIDEO-
In the past when the bandwidth of the operational amplifier
ended at a few hundred kHz even at few MHz, the powersupply bypass was not a very critical issue, since a 0.1µF
capacitor “did the job”, but today’s amplifiers could have
bandwidth, what used to be reserved for microwave circuits
not to long time ago.
Therefore that high bandwidth amplifiers require the same
respect what we reserve for microwave circuits. Particularly
the power supply bypass and the pcb-layout could very
heavily influence the performance of a modern high
bandwidth amplifiers. It could happen above a few MHz, but
it will happen above 100MHz, that the capacitor will behave
like an inductor.
The test result is shown on Figure 30.
By selecting a different value for C1, we could reduce the
effect, created by C3 R3 and get flat response from 16Hz

The reason for that is the very small but not zero value serial
inductance of the capacitor.

Above its serial resonance C2* the ideal capacitance of C2 is
a short, the Tantalum capacitor for high frequencies is not
effective, the left over is C1 capacitor and L1 + L2 inductors,
we get a parallel tank circuit, which is at it’s resonance a high
impedance path and do not carry any high frequency
current, it does not work as bypass at all!
The impedance of a parallel tank circuit at resonance is
dependent from it’s Q. High Q high impedance.

The capacitor will behave as a capacitor up to its resonance
frequency, above the resonance frequency it will behave as
an inductor.
Just 1nHy inductance serial with 1nF capacitance will have
serial resonance at:

F=
2π L × C
C = 1nF, L = 1nHy, F = 159 MHz
The Q of a parallel tank circuit could be reduced by
bypassing it with a resistor, or adding a resistor in serial to
one of the reactive components. Since the bypassing would
short the DC supply we do have to go to add resistor in serial
to the reactive component, we will ad a resistor serial with
the inductor. (See Figure 33.)

And an other 1nHy is very easy to get together with the
inductance of traces on the pcb, and therefore you could
encounter resonances from ca 50MHz and above anywhere.
So if the amplifier has a bandwidth of a few hundred MHz,
the proper power supply by-pass could become a serious if
not difficult task.
Intuitively, you would use capacitors value 0.1µF parallel
with a few µF tantalum, and to cure the effect of it’s serial
resonance put a smaller one parallel to it.
The result will surprise to you, because you will get even
something worse than without the small capacitor.
