Darlington amplifier circuit
WebBecause of this behavior, the common-collector amplifier circuit is also known as the voltage-follower or emitter-follower amplifier, ... A Darlington pair is a pair of transistors “piggybacked” on one another so that the emitter of one feeds current to the base of the other in common-collector form. The result is an overall current gain ... WebNov 15, 2024 · Darlington transistors T1 and T2 amplify the output current of NE5534. Output current The output current should be limited to around 4A. Diodes D1 through D3 and resistor R11 limit the output current of T1 (npn). Diodes D4 through D6 and resistor R12 limit the output current of T2 (pnp).
