  2. Push–pull output - Wikipedia

    en.wikipedia.org/wiki/Pushpull_output

    A conventional amplifier stage which is not pushpull is sometimes called single-ended to distinguish it from a pushpull circuit. In analog pushpull power amplifiers the two output devices operate in antiphase (i.e. 180° apart). The two antiphase outputs are connected to the load in a way that causes the signal outputs to be added, but ...

  3. 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 ...

    en.wikipedia.org/wiki/Power_MOSFET

    NXP 7030AL - N-channel TrenchMOS logic level FET IRF640 Power Mosfet die. The power MOSFET is the most widely used power semiconductor device in the world. [3] As of 2010, the power MOSFET accounts for 53% of the power transistor market, ahead of the insulated-gate bipolar transistor (27%), RF power amplifier (11%) and bipolar junction transistor (9%).

  5. 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.

  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. Amplifier - Wikipedia

    en.wikipedia.org/wiki/Amplifier

    The practical amplifier circuit shown above could be the basis for a moderate-power audio amplifier. It features a typical (though substantially simplified) design as found in modern amplifiers, with a class-AB pushpull output stage, and uses some overall negative feedback. Bipolar transistors are shown, but this design would also be ...

  8. 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 .

  9. 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.
