Darlington Pair Amplifier Design. Now place the second transistor in the breadboard, such that the collector terminals of both transistors are connected. We require high gain to drive high loads like an audio amplifier, power regulators, motor controller, etc.

The resulting transconductance which determines the voltage gain of a darlington stage is only 50% if compared with the capabilities of the second transistor and its own transonductance (this is the price to be paid for the large input resistance). Very high current gain allowing a pretty large input resistance. Benefits or advantages of darlington transistor.

You’ll have a lot harder time blowing up. The darlington resistor is a composite design comprising of two bipolar pairs associated so that the current enhanced by the principal transistor is intensified further with the second one. It uses few components and hence can be used for easy circuit designs. I tested these 2 buffers today.
