7.1.1 Compensation for Input Capacitance
The combination of an amplifier input capacitance and gain setting resistors adds a pole that can cause peaking or oscillation. To solve this problem, use a feedback capacitor with the following value to cancel that pole:
Equation 1.
For the LM6171, a feedback capacitor of 2 pF is recommended. Figure 7-1 illustrates the compensation circuit.
