What is CMOS ( Complementary Metal-Oxide-Semiconductor)?

CMOS is a sort of metal–oxide–semiconductor field-effect transistor fabrication that utilizes p-type and n-type MOSFETs for logic functions. CMOS method is utilized for developing integrated circuit (IC) chips, including microprocessors, microcontrollers, memory chips, and other digital logic circuits. CMOS technology is also used for analog circuits such as image sensors, data converters, RF circuits (RF CMOS).
