  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 ...

  3. 2N7000 - Wikipedia

    en.wikipedia.org/wiki/2N7000

    A typical use of these transistors is as a switch for moderate voltages and currents, including as drivers for small lamps, motors, and relays. [1] In switching circuits, these FETs can be used much like bipolar junction transistors, but have some advantages: high input impedance of the insulated gate means almost no gate current is required

  5. Sample and hold - Wikipedia

    en.wikipedia.org/wiki/Sample_and_hold

    A typical sample and hold circuit stores electric charge in a capacitor and contains at least one switching device such as a FET (field effect transistor) switch and normally one operational amplifier. [2] To sample the input signal, the switch connects the capacitor to the output of a buffer amplifier. The buffer amplifier charges or ...

  6. Schottky transistor - Wikipedia

    en.wikipedia.org/wiki/Schottky_transistor

    In 1956, Richard Baker described some discrete diode clamp circuits to keep transistors from saturating. [2] The circuits are now known as Baker clamps.One of those clamp circuits used a single germanium diode to clamp a silicon transistor in a circuit configuration that is the same as the Schottky transistor.

  8. TL431 - Wikipedia

    en.wikipedia.org/wiki/TL431

    The typical initial deviation of reference voltage from the nominal 2.495 V level is measured in millivolts, the maximum worst-case deviation is measured in tens of millivolts. The circuit can control power transistors directly; combinations of the TL431 with power MOS transistors are used in high efficiency, very low dropout linear regulators.
