  2. Push–pull output - Wikipedia

    en.wikipedia.org/wiki/Pushpull_output

    A Class B pushpull output driver using a pair of complementary PNP and NPN bipolar junction transistors configured as emitter followers. A pushpull 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 ...

  3. FET amplifier - Wikipedia

    en.wikipedia.org/wiki/FET_amplifier

    The most common type of FET amplifier is the MOSFET amplifier, which uses metal–oxide–semiconductor FETs (MOSFETs). The main advantage of a FET used for amplification is that it has very high input impedance and low output impedance .

  4. Shunt regulated push-pull amplifier - Wikipedia

    en.wikipedia.org/wiki/Shunt_regulated_push-pull...

    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.

  5. MOSFET - Wikipedia

    en.wikipedia.org/wiki/MOSFET

    If the MOSFET is an n-channel or nMOS FET, then the source and drain are n+ regions and the body is a p region. If the MOSFET is a p-channel or pMOS FET, then the source and drain are p+ regions and the body is a n region. The source is so named because it is the source of the charge carriers (electrons for n-channel, holes for p-channel) that ...

  6. Depletion and enhancement modes - Wikipedia

    en.wikipedia.org/wiki/Depletion_and_enhancement...

    Enhancement-mode MOSFETs (metal–oxide–semiconductor FETs) are the common switching elements in most integrated circuits. These devices are off at zero gate–source voltage. NMOS can be turned on by pulling the gate voltage higher than the source voltage, PMOS can be turned on by pulling the gate voltage lower than the source voltage.

  7. List of MOSFET applications - Wikipedia

    en.wikipedia.org/wiki/List_of_MOSFET_applications

    MOSFET, showing gate (G), body (B), source (S), and drain (D) terminals. The gate is separated from the body by an insulating layer (pink).. The MOSFET (metal–oxide–semiconductor field-effect transistor) [1] is a type of insulated-gate field-effect transistor (IGFET) that is fabricated by the controlled oxidation of a semiconductor, typically silicon.

  8. Crossover distortion - Wikipedia

    en.wikipedia.org/wiki/Crossover_distortion

    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.

  9. CMOS amplifier - Wikipedia

    en.wikipedia.org/wiki/CMOS_amplifier

    CMOS amplifiers (complementary metal–oxide–semiconductor amplifiers) are ubiquitous analog circuits used in computers, audio systems, smartphones, cameras, telecommunication systems, biomedical circuits, and many other systems. Their performance impacts the overall specifications of the systems.
