What is the usual remedy for a feedback amplifier driving a capacitive load?
Answer: B
Placing a small resistor between the output and the load, with the feedback taken from inside it, keeps the load's pole outside the loop where its phase does no harm. A capacitor across the feedback resistor is a useful lead network for a different problem, a larger feedback resistor changes the gain, and headroom is unrelated. Moving a troublesome element outside a loop is often easier than compensating for it inside, and it costs only a little output impedance.
