WebA Darlington Transistor configuration, also known as a “Darlington pair” or “super-alpha circuit”, consist of two NPN or PNP transistors connected together so that the emitter current of the first transistor TR1 becomes the base current of the second transistor TR2. Then transistor TR1 is connected as an emitter follower and TR2 as a ... In electronics, a common collector amplifier (also known as an emitter follower) is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as a voltage buffer. In this circuit the base terminal of the transistor serves as the input, the emitter is the output, and the collector is common to both (for example, it may be tied to ground …

"WebMar 21, 2024 · By using a PNP, its collector voltage must be less than its emitter voltage. As we're also using a bipolar power supply, we can eliminate the need for the final output coupling capacitor. All we need to do is set up the resistor values such that the drop across R C 2 is the same as V E E. " - Pnp collector follower

WebMay 22, 2024 · Let's begin by making two bare-bones emitter followers, one NPN and the other PNP. We'll connect their emitters together and tie that to the load. We'll connect the NPN's collector directly to a DC supply and the PNP's collector to ground. Remember, collector resistors will not be needed because these are followers.
