    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. Threshold voltage - Wikipedia

    en.wikipedia.org/wiki/Threshold_voltage

    In a given technology node, such as the 90-nm CMOS process, the threshold voltage depends on the choice of oxide and on oxide thickness. Using the body formulas above, V T N {\displaystyle V_{TN}} is directly proportional to γ {\displaystyle \gamma } , and t O X {\displaystyle t_{OX}} , which is the parameter for oxide thickness.

  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. 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 ...

  6. Dynamic logic (digital electronics) - Wikipedia

    en.wikipedia.org/wiki/Dynamic_logic_(digital...

    In general, dynamic logic greatly increases the number of transistors that are switching at any given time, which increases power consumption over static CMOS. [8] There are several powersaving techniques that can be implemented in a dynamic logic based system. In addition, each rail can convey an arbitrary number of bits, and there are no ...

  7. CMOS amplifier - Wikipedia

    en.wikipedia.org/wiki/CMOS_amplifier

    The transistor channel length is smaller in modern CMOS technologies, which makes achieving high gain in single-stage amplifiers very challenging. To achieve high gain, the literature has suggested many techniques. [6] [7] [8] The following sections look at different amplifier topologies and their features.

  9. Dennard scaling - Wikipedia

    en.wikipedia.org/wiki/Dennard_scaling

    The dynamic (switching) power consumption of CMOS circuits is proportional to frequency. [8] Historically, the transistor power reduction afforded by Dennard scaling allowed manufacturers to drastically raise clock frequencies from one generation to the next without significantly increasing overall circuit power consumption.
