Abstract

This paper presents a self-biased current-mode amplifier (CMAMP) suitable for a switched-capacitor circuit. The CMAMP uses a subthreshold-biased transimpedance stage as a current-sensing load, and minimizes static power dissipation by passing bias current only at the input stage. The first-order system behavior with single dominant pole gives stable phase margin without complicated frequency compe...
