It consists of two transistors in which one is NPN and the other is PNP. While the use of these components is extensive, the first choice when it comes to delivering power to these, is a push-pull transistor circuit. It is also known as Push-Pull Amplifier and in TTL (Transistor Transistor Logic) circuits, it is called “‘ Totem Pole Output” based on transistors, diodes and resistors.Ī servo amplifiers is used widely because of a special trait that lets them transfer energy to load or even absorb power from the load at times. It used to supply high power to the load. *This information is for general informational purposes only, we will not be liable for any loss or damage caused by the above information.Push-Pull Amplifier Circuits using TransistorsĪ Push-Pull transistor circuit is an electronic circuit that uses active devices connected in a particular way that alternatively supply current and absorb from connected load whenever needed.
