Darlington complementary is the basic order in how the output stage of an amplifier is taught. All output transistors are arranged as emitter followers. The collectors are connected directly to the rails. The emitter follows the signal on base within 650mV. The output transistors do not increase the size of the audio signal.

Function: The output or sometimes called the power-amplifier stage follows the detector, and is the last stage in the signal path of the receiver. The signal level from the preceding detector stage would be about sufficient to operate a pair of headphones, so this signal must be amplified to a sufficient level to drive a loud speaker.

output impedance is low. As a bonus, its input impedance is relatively high. Principal advantage – lower distortion than Class B & AB. Principal disadvantage – lower power efficiency than Class B & AB. Used as op amp output stage and some audio output power amps.
