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 ...

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 ...
Valve hi-fi power amplifier designs since the 1970s have had to move mainly to class AB1 push–pull (PP) circuits. Tetrodes and pentodes, sometimes in ultra-linear configuration, with significant negative feedback, are the usual configuration. Some class A push–pull amplifiers are made commercially.
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.
A single EL84 was used in low-cost equipment, and a push–pull pair for lower distortion and higher power. In common with all 'E' prefix tubes, using the Mullard–Philips tube designation, it has a heater voltage of 6.3V. It can produce 17W output in Class AB1 in push–pull configuration. Many guitar-amplifiers routinely run EL84 tubes in ...
For a distributed amplifier the input is fed in series into the amplifiers and parallel out of them. To avoid losses in the input, no input signal is allowed to leak through. This is avoided by using a balanced input and output also known as push–pull amplifier. Then all signals which leak through the parasitic capacitances cancel.
