Abstract

Abstract : A super class AB recycling folded cascode operational transconductance amplifier is presented. It employs local common‐mode feedback using two matched tuneable active resistors, allowing to adapt the amplifier to different process variations and loads. Measurement results from a test chip prototype fabricated in a 0.5 μm CMOS process validate the proposal.
