  2. MOSFET - Wikipedia

    These regions can be either p or n type, but they must both be of the same type, and of opposite type to the body region. The source and drain (unlike the body) are highly doped as signified by a "+" sign after the type of doping. 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.

  3. Power MOSFET - Wikipedia

    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%). [24]

  4. 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.

  5. Depletion and enhancement modes - Wikipedia

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

    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. In most circuits, this means pulling an enhancement-mode MOSFET's gate voltage towards its drain voltage turns it on.

  6. Field-effect transistor - Wikipedia

    en.wikipedia.org/wiki/Field-effect_transistor

    Cross-sectional view of a MOSFET type field-effect transistor, showing source, gate and drain terminals, and insulating oxide layer. The field-effect transistor (FET) is a type of transistor that uses an electric field to control the current through a semiconductor. It comes in two types: junction FET (JFET) and metal-oxide-semiconductor FET ...

  7. Subthreshold slope - Wikipedia

    en.wikipedia.org/wiki/Subthreshold_slope

    The subthreshold slope is a feature of a MOSFET's current–voltage characteristic.. In the subthreshold region, the drain current behaviour—though being controlled by the gate terminal—is similar to the exponentially decreasing current of a forward biased diode.

  8. Overdrive voltage - Wikipedia

    en.wikipedia.org/wiki/Overdrive_voltage

    Overdrive voltage, usually abbreviated as V OV, is typically referred to in the context of MOSFET transistors.The overdrive voltage is defined as the voltage between transistor gate and source (V GS) in excess of the threshold voltage (V TH) where V TH is defined as the minimum voltage required between gate and source to turn the transistor on (allow it to conduct electricity).

  9. Open collector - Wikipedia

    en.wikipedia.org/wiki/Open_collector

    Push–pull output: Consists of transistors to source and sink current in both logic states, not just one. Three-state logic: Consists of transistors to source and sink current in both logic states, as well as a control to turn off both transistors to isolate the output. This differs from open collector/drain output, which only use a single ...
