Abstract

The output stage of an operational amplifier has to provide the load impedance Z _L with the desired output voltage V _O and current I _O, resulting in an output power P _O = V _O I _O. The main requirements of the output stage are: the ability to deliver negative and positive output currents at a high current efficiency, an output voltage range that efficiently utilizes the range between the negative supply rail voltage and the positive one, a high power efficiency, a low distortion, and good high-frequency (HF) performance.
