metal-oxide-semiconductor (CMOS) (pronounced
"see-moss", IPA: /si?M??S, ?Si?M?S/), is a major class of integrated circuits. CMOS technology is used in microprocessors,
microcontrollers, static RAM, and other digital logic circuits. CMOS technology is also used for a wide variety of
analog circuits such as image sensors, data converters, and highly integrated
transceivers for many types of communication. Frank Wanlass successfully
patented CMOS in 1967 (US Patent 3,356,858).
