  2. Transistor - Wikipedia

    en.wikipedia.org/wiki/Transistor

    The bipolar junction transistor, the first type of transistor to be mass-produced, is a combination of two junction diodes and is formed of either a thin layer of p-type semiconductor sandwiched between two n-type semiconductors (an n–p–n transistor), or a thin layer of n-type semiconductor sandwiched between two p-type semiconductors (a p ...

  3. MOSFET - Wikipedia

    en.wikipedia.org/wiki/MOSFET

    In electronics, the metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, MOS FET, or MOS transistor) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon. It has an insulated gate, the voltage of which determines the conductivity of the device.

  4. Bipolar junction transistor - Wikipedia

    en.wikipedia.org/wiki/Bipolar_junction_transistor

    3D model of a TO-92 package, commonly used for small bipolar transistors. A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor (FET), uses only one kind of charge carrier.

  5. PMOS logic - Wikipedia

    en.wikipedia.org/wiki/PMOS_logic

    PMOS transistors operate by creating an inversion layer in an n-type transistor body. This inversion layer, called the p-channel, can conduct holes between p-type "source" and "drain" terminals. The p-channel is created by applying a negative voltage (-25V was common [ 18 ] ) to the third terminal, called the gate.

  6. Emitter-coupled logic - Wikipedia

    en.wikipedia.org/wiki/Emitter-coupled_logic

    In electronics, emitter-coupled logic (ECL) is a high-speed integrated circuit bipolar transistor logic family. ECL uses an overdriven bipolar junction transistor (BJT) differential amplifier with single-ended input and limited emitter current to avoid the saturated (fully on) region of operation and the resulting slow turn-off behavior.

    Schematic diagram of a single-electron transistor Left to right: energy levels of source, island and drain in a single-electron transistor for the blocking state (upper part) and transmitting state (lower part). The SET has, like the FET, three electrodes: source, drain, and a gate. The main technological difference between the transistor types ...
