Fully differential basic building blocks based on fully differential difference amplifiers with unity-gain difference feedback

Abstract

A set of truly fully differential (FD) basic building blocks is presented. They are based on differential difference amplifiers with differential output (FDDA, fully differential difference amplifier) in unity gain difference feedback configuration. Simulation results at the transistor level demonstrate their suitability for FD signal processing.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
