A Class B push–pull output driver using a pair of complementary PNP and NPN bipolar junction transistors configured as emitter followers. A push–pull amplifier is a type of electronic circuit that uses a pair of active devices that alternately supply current to, or absorb current from, a connected load. This kind of amplifier can enhance ...

A shunt regulated push-pull amplifier is a Class A amplifier whose output drivers (transistors or more commonly vacuum tubes) operate in antiphase. The key design element is the output stage also serves as the phase splitter. The acronym SRPP is also used to describe a series regulated push-pull amplifier.
English: Circuit diagram of a push-pull DC to DC converter. This is used in battery-powered electronic devices such as laptops to convert DC power to a higher voltage. The switches (left) represent pairs of switching transistors, with the driving circuits omitted. They are switched simultaneously at a high frequency of 10 - 80 kHz They switch ...

Class-B amplifiers are also favoured in battery-operated devices, such as transistor radios. Class B has a maximum theoretical efficiency of π/4 (≈ 78.5%). [15] A practical circuit using class-B elements is the push–pull stage, such as the very simplified complementary pair arrangement shown at right. Complementary devices are each used ...
In the example shown, the operational amplifier is used to reduce the distortion of a push-pull pair. Operational amplifiers are differential voltage amplifiers with very high gain (sometimes modeled as infinite gain). In an ideal model, the output of the op amp is held such that both inputs of the op amp must be at exactly the same voltage.
Push–pull power amplifier. The push–pull output circuit shown is a simplified variation of the Williamson topology, which comprises four stages: a SET input stage to buffer the input and give some voltage gain. a phase splitter, usually of the cathodyne or "concertina" type.
