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 ...
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 ...
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. [3] Like any unity buffer, the diamond buffer does not alter the phase and magnitude of input ...
Sziklai pair that acts like a single NPN transistor with collector C, emitter E, and base B. In electronics, the Sziklai pair, also known as a complementary feedback pair, is a configuration of two bipolar transistors, similar to a Darlington pair. [1] In contrast to the Darlington arrangement, the Sziklai pair has one NPN and one PNP ...
Shunt regulated push-pull amplifier. 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.
Tube sound (or valve sound) is the characteristic sound associated with a vacuum tube amplifier (valve amplifier in British English), a vacuum tube -based audio amplifier. [1] At first, the concept of tube sound did not exist, because practically all electronic amplification of audio signals was done with vacuum tubes and other comparable ...
Crossover distortion is a type of distortion which is caused by switching between devices driving a load. [1] It is most commonly seen in complementary, or "push-pull", class-B amplifier stages, although it is occasionally seen in other types of circuits as well. Input–output characteristic of a class-B complementary emitter follower stage.
The Williamson amplifier is a four-stage, push-pull, Class A triode-output valve audio power amplifier designed by D. T. N. Williamson during World War II. The original circuit, published in 1947 and addressed to the worldwide do it yourself community, set the standard of high fidelity sound reproduction and served as a benchmark or reference ...
