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 ...
A Constant-gm CMOS Operational amplifier with Rail-to-Rail input common-mode voltage range has been designed. The input stage is based on two pairs of single p-channel differential pairs and two identical n-channel source followers as DC level shifters, ...
This work presents a high-voltage (HV) operational amplifier (OPA). OPAs are widely used in signal conditioning circuits for industrial applications and integrated circuits (ICs). Particularly, in HV applications like BMS (battery management system), ...
