Abstract

A new frequency-compensation topology (NGRNMC) is proposed, which improves the frequency characteristics and transient response of multistage amplifiers while minimizing the power consumption. Comparisons are made to demonstrate the advantages of the topology. A three-stage fully-differential NGRNMC amplifier, driving two 16 pF capacitors with 80 MHz GBW, is fabricated in a 0.35 /spl mu/m CMOS process, confirming the experimental results. Criteria are proposed to accurately evaluate and compare amplifiers implemented in different operating conditions.
