Darlington amplifier is an emitter follower
Darlington pairs are often used in the push-pull output stages of the power audio amplifiers that drive most sound systems. In a fully symmetrical push-pull circuit two Darlington pairs are connected as emitter followers driving the output from the positive and negative supply: an NPN Darlington pair connected to the positive rail providing current for positive excursions of the output, and a PNP Darlington pair connected to the negative rail providing current for negative e… WebApr 6, 2024 · A Darlington pair is a two-transistor circuit with the emitter of one transistor is connected to the base of another transistor, while both collector terminals are connected to the common terminal. It has high current gain β; (equal to the product of current gain of individual transistors)
