  2. Touch switch - Wikipedia

    en.wikipedia.org/wiki/Touch_switch

    Video demonstrating the operation of a touch-sensitive lamp A touch-sensitive lamp is a combination of a lamp and a touch switch. They act on the principle of body capacitance, activated by human touch rather than a flip, push-button, or other mechanical switch. They are popular as desk and nightstand lamps. Touch-sensitive lamp switches may be ...

    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.

  4. Multi-threshold CMOS - Wikipedia

    en.wikipedia.org/wiki/Multi-threshold_CMOS

    Multi-threshold CMOS (MTCMOS) is a variation of CMOS chip technology which has transistors with multiple threshold voltages (V th) in order to optimize delay or power.The V th of a MOSFET is the gate voltage where an inversion layer forms at the interface between the insulating layer (oxide) and the substrate (body) of the transistor.

  5. TL431 - Wikipedia

    en.wikipedia.org/wiki/TL431

    The TL431 is functionally equivalent to an ideal npn bipolar transistor switch with a stable 2.495 V switching threshold and no apparent hysteresis. "Base", "collector" and "emitter" of this "transistor" are traditionally called reference (R or REF), cathode (C) and anode (A). [ 5 ]

  7. Radio-frequency microelectromechanical system - Wikipedia

    en.wikipedia.org/wiki/Radio-frequency_micro...

    From an RF perspective, the components behave like a series RLC circuit with negligible resistance and inductance. The up- and down-state capacitance are in the order of 50 fF and 1.2 pF, which are functional values for millimeter-wave circuit design. Switches typically have a capacitance ratio of 30 or higher, while switched capacitors and ...

    en.wikipedia.org/wiki/555_timer_IC

    The 555 timer IC is an integrated circuit used in a variety of timer, delay, pulse generation, and oscillator applications. It is one of the most popular timing ICs due to its flexibility and price. It is one of the most popular timing ICs due to its flexibility and price.

  9. Point-contact transistor - Wikipedia

    en.wikipedia.org/wiki/Point-contact_transistor

    The common base current gain (or α) of a point-contact transistor is usually around 2 to 3, [4] whereas α of bipolar junction transistor (BJT) cannot exceed 1. The common emitter current gain (or β) of a point-contact transistor does not usually exceed 1, [4] whereas β of a BJT is typically between 20 and 200. Negative differential ...
