Active-feedback frequency-compensation technique for low-power multistage amplifiers.

Active-feedback frequency-compensation technique for low-power multistage amplifiers.

An active-feedback frequency-compensation (AFFC) technique for low-power operational amplifiers is presented in this paper. With an active-feedback mechanism, a high-speed block separates the low-frequency high-gain path and high-frequency signal path such that high gain and wide bandwidth can be ac...
