  2. CMOS - Wikipedia

    en.wikipedia.org/wiki/CMOS

    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. [2]

  3. 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.

  4. Subthreshold conduction - Wikipedia

    en.wikipedia.org/wiki/Subthreshold_conduction

    The amount of subthreshold conduction in a transistor is set by its threshold voltage, which is the minimum gate voltage required to switch the device between on and off states. However, as the drain current in a MOS device varies exponentially with gate voltage, the conduction does not immediately become zero when the threshold voltage is reached.

  5. Single-electron transistor - Wikipedia

    en.wikipedia.org/wiki/Single-electron_transistor

    A single-electron transistor (SET) is a sensitive electronic device based on the Coulomb blockade effect. In this device the electrons flow through a tunnel junction between source/drain to a quantum dot (conductive island). Moreover, the electrical potential of the island can be tuned by a third electrode, known as the gate, which is ...

  6. HCMOS - Wikipedia

    en.wikipedia.org/wiki/HCMOS

    HCMOS ("high-speed CMOS") is the set of specifications for electrical ratings and characteristics, forming the 74HC00 family, a part of the 7400 series of integrated circuits. [ 1 ] The 74HC00 family followed, and improved upon, the 74C00 series (which provided an alternative CMOS logic family to the 4000 series but retained the part number ...

  7. 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.

  8. 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.

  9. 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 ...
