One such application is it can be used as a very high-performance voltage follower. The Darlington Amplifier provides 1) Very High Input Impedance 2) Low Output Impedance 3) Close to or less than unity Voltage Gain 4) Very High Current Gain Because of these properties, it acts as a very good buffer. In this video, the DC, as well as the AC / Small signal analysis of the Darlington Amplifier, is explained. And the equation of the voltage gain, the current gain, the input, and output impedance of the Darlington Amplifier is derived.
