WebThe Darlington amplifier circuit in its small signal ac form will appear, as shown in Fig. 19.51. Main Characteristics: 1. Current Gain: For the second stage: Input impedance, and … WebDarlington pairs essentially place one transistor as the common-collector load for another transistor, thus multiplying their current gains. The base current through the upper-left transistor is amplified through that transistor’s emitter, which is directly connected to the base of the lower-right transistor, where the current is again amplified.
WebDec 22, 2024 · It was invented by Sydney Darlington and patented by Bell Labs in 1953. This arrangement behaves like a single transistor with a current gain given by the product of the gains of the two transistors. Gains of several thousand are easily achieved—really useful when driving high-powered loads such as in audio amplifiers and the like.
