Cmos

CMOS Logic Circuits * CMOS stands for Complementary Metal Oxide Semiconductor is a apply science for constructing integrated circuits. CMOS technology is used in microprocessors, microcontrollers, static RAM, and different(a) digital logic circuits. CMOS technology is also used for several(prenominal) analog circuits such as image sensors (CMOS sensor), data converters, and risquely integrated transceivers for many an(prenominal) types of communication. Frank Wanlass  unembellisheded CMOS in 1967 (US patent 3,356,858). CMOS is also sometimes referred to as complementary-symmetry metaloxidesemiconductor (or COS-MOS).The talking to complementary-symmetry refer to the fact that the regular digital design musical mode with CMOS uses complementary and cruciform pairs of p-type and n-type metal oxide semiconductor field kernel transistors (MOSFETs) for logic functions. two important characteristics of CMOS devices are high  ring immunity and impove rished static  fountain consumption. Significant power is only move when the transistors in the CMOS device are reverse between on and off states. Consequently, CMOS devices do not call forth as much waste heat as other forms of logic, for exemplar transistor-transistor logic (TTL) or NMOS logic. CMOS also allows a high dumbness of logic functions on a chip. It was primarily for this author that CMOS became the most(prenominal) used technology to be implemented in VLSI chips.

The artistic style metaloxidesemiconductor is a reference to the forcible body structure of certain field-effect transistor s, having a metal approach electrode displ! ace on carrousel of an oxide insulator, which in turn is on top of a semiconductor material. Aluminium was once used simply instantaneously the material is polysilicon. Other metal gates  open do a comeback with the advent of high-k dielectric materials in the CMOS process, as announced by IBM and Intel for the 45 nanometre  guest and beyond.
