Low-Voltage Class AB Operational Amplifier

A low-voltage fully differential CMOS operational amplifier with constant-g _m and rail-to-rail input and output stages is presented. It is the fully differential version of a previously realized single-ended operational amplifier where a novel circuit ...

This paper presents a new low-voltage class AB fully-balanced differential difference amplifier (FB-DDA) employing the bulk-driven technique. At the FB-DDA differential pairs the bulk terminal of the MOS transistors are used as signal inputs in order to ...

A novel CMOS current-feedback operational amplifier (CFOA) aimed to low-power applications is proposed. The use of a compact class AB implementation allows high current-drive capability and simultaneously very low quiescent power consumption. Measurement ...
