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 ...
The opposing currents in the primary windings always balance but the whole primary "sees" the complete sinewave. In this manner, a sinewave is able to be generated while allowing the transistors to switch alternately fully on and off in push-pull mode. This is the only resemblance to the Royer converter.
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 ...
A push–pull converter is a type of DC-to-DC converter, a switching converter that uses a transformer to change the voltage of a DC power supply. The distinguishing feature of a push-pull converter is that the transformer primary is supplied with current from the input line by pairs of transistors in a symmetrical push-pull circuit .
A 555 timer can act as an active-low SR latch (though without an inverted Q output) with two outputs: output pin is a push-pull output, discharge pin is an open-collector output (requires a pull-up resistor). For the schematic on the right, a Reset input signal connects to the RESET pin and connecting a Set input signal to the TR pin.
[1] [2] Both circuits drawn to underscore the bridged topology of push-pull operation. The diamond buffer or diamond follower is a four-transistor, two-stage, push-pull, translinear emitter follower, or less commonly source follower, in which the input transistors are folded, or placed upside-down with respect to the output transistors.

In a push-push stage, the output will only contain even harmonics. This is because the currents which would generate the fundamental and the odd harmonics in this circuit are canceled by the second device. In a push-pull stage, the output will contain only odd harmonics because of the canceling effect.
