The circuit used in the LOG114EVM is designed to operate over a wide range of input currents (10 nA to 10 mA) and scales the output voltage from 1.15 V to 2.75 V. There are three distinct sections to the LOG114EVM circuit: a precision level shifter, the signal path, and the high-current linearity correction section. Each section is described below to familiarize you with the circuit functionality and operation. 2.1 Level Shifter A precision level shifter is required to operate the LOG114 on a single power supply. On the LOG114EVM, the level shifter circuit is constructed by deriving a bias voltage of 2 V from the 2.5-V voltage reference internal to the LOG114. This level shift of 2 V is required to keep the nodes internal to the LOG114 properly biased when operating from a single power supply. Resistors R9 and R10 form a voltage divider that is then buffered by the OPA365 amplifier. The output of the OPA365 is a fixed voltage of 2 V, independent of the power-supply voltage or input signal. C2 is used to bypass the power supply for the OPA365. The level shifter circuit is shown in Figure 2. 2.5 V from LOG114 VREF + C2 100 nF R10 1 kW R9 4.02 kW OPA365 VCC +5 V VBIAS Figure 2. LOG114EVM Level Shifter 2.2 Signal Path The LOG114 has two inputs, I1 and I2. Input I1 is used for the input signal (usually from a photodiode) and I2 is a fixed-current reference signal. This fixed-current reference signal is derived from the 2.5-V voltage reference internal to the LOG114 and the 2-V output from the level shifter. The reference current into I2 is given by Equation 1. (2.5 V - 2 V) IREF = = 500 nA 1 MW (1) The input current must flow into I1 and comes directly from the anode of a photodiode. In non-optical applications, the input current could also be derived from a resistor, or a variety of other sources (see Section 3.4). For proper operation, each input to the LOG114 (I1 and I2) requires the current to flow into the LOG114. The output from the LOG114 amplifier A3 is called VLOGOUT. The relationship between VLOGOUT, I1 and I2, and the bias voltage generated by the level shifter is described by Equation 2. I VLOGOUT = 0.375·LOG10 2 + 2 V I1 (2) ( ( SBOU110 – September 2011 Submit Documentation Feedback LOG114EVM User Guide Copyright © 2011, Texas Instruments Incorporated 3 LOG114EVM www.ti.com The VLOGOUT output is then scaled by resistors R7 and R8. These resistors divide the signal before combining with the high-current linearity correction section. Combining the input signal and linearity correction signal is accomplished with amplifier A4 and resistors R5 and R6. Capacitor C1 is used to bypass the power supply for the LOG114. The signal path circuit is shown in Figure 3.

LOG114EVM Signal Path 2.3 High-Current Linearity Correction The LOG114 is capable of handling a wide dynamic range of currents, from less than 100 pA in a carefully designed PCB to 10 mA in high-current applications. Because the LOG114 was designed for high speeds, the transistors that provide feedback around amplifiers A1 and A2 within the LOG114 have a small series resistance, RS. This small series resistance causes a deviation from the ideal LOG114 transfer function at input currents that exceed approximately 1 mA. The modified equation for VLOGOUT that shows this deviation from the ideal is given in Equation 3. I VLOGOUT = 0.375·LOG10 2 + 2 V + I1·RS I1 (3) ( ( 4 LOG114EVM User Guide Copyright © 2011, Texas Instruments Incorporated SBOU110 – September 2011 Submit Documentation Feedback LOG114EVM www.ti.com The high-current linearity correction circuit (refer to Figure 4) creates an error signal that is proportional to input current I1 by using R2, R3 and R4, and amplifier A5. Resistor R1 is used to properly level-shift the resulting output signal. The signal at the output from amplifier A5 is then coupled to the input of amplifier A4 in a manner that subtracts the error signal from the output of the EVM, VOUT.

As Figure 10 shows, a 1-MΩ resistor is placed between VREF and the input I1. In this case, the input current I1 is determined by Equation 4. (V - VBIAS) I1 = REF R (4) Figure 10.

The circuit in Figure 10, while convenient for creating an input current, does not take advantage of the high-current linearity correction circuitry. To use this circuitry, a second power supply must be used and configured as shown in Figure 11. + + VIN Figure 11. Using a Resistor and the High Current Linearity Correction Circuitry Changing the input voltage or the resistor value changes the input current I1 (I1 = VIN/R) and results in a change for the VLOGOUT terminal voltage according to Equation 5. I VLOGOUT = 0.375·LOG10 2 + 2 V + I1·50 W I1 (5) ( ( For input currents less than 1 mA, this equation simplifies to Equation 2.
