چکیده
A novel class-AB transconductance amplifier, suitable for the input stage of high slew rate CMOS operational amplifier is proposed. The proposed class-AB transconductor is realized from a differential pair of mixed translinear common-drain push-pull circuit. A high speed operational amplifier employing the proposed input stage and a complementary common –source high gain stage is presented. HSPICE simulation results of such an operational amplifier are given. Keyword: CMOS op-amp, High speed amplifier
