Due to this effect, the signal gets distorted at 0V. It generally suffers from an effect known as Crossover Distortion. The conduction angle for this amplifier is 180 degrees, because each transistor works for one half only.Ĭlass B amplifier is one of the most used amplifiers, but it comes with its own shortcoming. This improves the efficiency of the Class B amplifier many times higher than the Class A amplifier. In contrast to Class A amplifier, Class B amplifier has two transistors for the push-pull electrical action of which one is NPN and the other is PNP.Įach transistor will work for one half of the cycle of the input producing the necessary output. There are many types of push-pull amplifier circuits but we will consider the following ones related to push-pull amplifier circuits:Īlthough all the configurations of the push-pull amplifier can technically be called push-pull amplifier, only the Class B amplifier is the actual push-pull amplifier. There are three types of push-pull amplifier but generally, Class-B amplifier is considered as push-pull amplifier. The main advantage of this transistor circuit is that there is no power dissipation at the output transistor, when there is no signal.

One transistor pushes the output on positive half cycle and other pulls on the negative half cycle, hence the name push-pull amplifier. 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. These are additional considerations to include in a fuller analysis not done here.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. We don't know if this is important, or not, just yet.

One of the first things to understand is the capability of the output, as that is what will be driving other inputs. Simulate this circuit – Schematic created using CircuitLab Let me draw out the schematic using the editor (you should have done this, too.)
