AC Simulation Results
The following plot shows the open-loop, AC, gain and phase plot of the circuit. The phase margin is found to be ≈ 62°. The rate-of-closure at fcl (AOLB = 0dB) is 20dB/decade between AOL and 1/β. As discussed previously, components Riso, RF, and CF compensate the circuit and ensure stability. For more details, see TI Precision Labs - Op Amps: Stability - Introduction.
