In this brief, a dual AC boosting compensation (DACBC) scheme is presented for multistage amplifiers with low power and a large capacitive load. Dual AC boosting paths are introduced to move the zero from the right-half-plane to the left-half-plane as compared with conventional AC boosting compensation (ACBC) scheme, which helps to improve the phase margin and gain bandwidth (GBW) product of the amplifier. Two three-stage amplifiers with DACBC and ACBC, respectively, are both fabricated in 65… CONTINUE READING
