CMOS operational amplifiers with continuous-time capacitive common mode feedback

Abstract

A simple and power efficient approach for the implementation of continuous-time common mode feedback networks using a capacitive averaging network is introduced. It is shown that low voltage, continuous-time, fully differential rail to rail operation can be achieved using the proposed technique. This at the expense of very small additional hardware and no… (More)
