Jaeger/Blalock 7/28/10 Microelectronic Circuit Design, 4E McGraw-Hill 235 -2 Op Amp Output Stages Output stage is designed to provide low output resistance and relatively high current drive capability. Followers: Class-A amplifiers- transistors conduct during full 3600 of signal waveform, conduction angle =3600. Push-pull: Class-B- each of the two transistors conducts during 1800of signal wavefrom, conduction angle =1800. Class-AB: Characteristics of Class-A and Class-B are combined, most commonly used as output stage in op amps.
