    CMOS inverter (a NOT logic gate). Complementary metal–oxide–semiconductor (CMOS, / ˈ s iː m ɒ s /, also US: /-ɔː s / [1]) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions.

  3. Translinear circuit - Wikipedia

    en.wikipedia.org/wiki/Translinear_circuit

    A translinear circuit is a circuit that carries out its function using the translinear principle. These are current-mode circuits that can be made using transistors that obey an exponential current-voltage characteristic—this includes bipolar junction transistors (BJTs) and CMOS transistors in weak inversion.

  4. CMOS amplifier - Wikipedia

    en.wikipedia.org/wiki/CMOS_amplifier

    In high performance CMOS (complementary metal–oxide–semiconductor) amplifier circuits, transistors are not only used to amplify the signal but are also used as active loads to achieve higher gain and output swing in comparison with resistive loads. [1] [2] [3] CMOS technology was introduced primarily for digital circuit design.

  5. AND-OR-invert - Wikipedia

    en.wikipedia.org/wiki/AND-OR-Invert

    In NMOS logic, the lower half of the CMOS circuit is used in combination with a load device or pull-up transistor (typically a depletion load or a dynamic load). AOI gates are similarly efficient in transistortransistor logic (TTL). Examples. CMOS 4000-series logic family: CD4085B = dual 2-2 AOI gate [3] CD4086B = single expandable 2-2-2-2 ...

    Schematic of two stages of CMOS inverter, showing input and output voltage-time plots. I on and I off (along with I DG, I SD and I DB components) indicate technologically controlled factors.

  7. Logic family - Wikipedia

    en.wikipedia.org/wiki/Logic_family

    Transistortransistor logic uses bipolar transistors to form its integrated circuits. [12] TTL has changed significantly over the years, with newer versions replacing the older types. Since the transistors of a standard TTL gate are saturated switches, minority carrier storage time in each junction limits the switching speed of the device.

  8. 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.

  9. Wilson current mirror - Wikipedia

    en.wikipedia.org/wiki/Wilson_current_mirror

    When the Wilson current mirror is used in CMOS circuits, it is usually in the four transistor form as in Fig. 5. [10] If the transistor pairs M1/M2 and M3/M4 are exactly matched and the input and output potentials are approximately equal, then in principle there is no static error, the input and output currents are equal because there is no low ...
