the Type 3 Conventional Operational Amplifier Compensation introduce 3 poles and 2 two zreos. it uses 2 pole to Compensate two zeros in dc-dc and uses 2 zeros to Compensate poles in dc-dc . I want to ask two questions: 1. when design the Compensation circuit , the operational amplifier has its own poles and zeros besides the 3 poles and 2 two zreos, how to do with the poles and zeros of the operational amplifier. 2. there are two pole-at-zero when the dc-dc is Compensated. the pole-at-zeros have bad effect on transient response of the loop. whether the two pole-at-zero have bad effect on transient response of the loop.?
