What is CMOS?

CMOS (Complementary Metal-Oxide-Semiconductor) is a type of semiconductor technology used to build integrated circuits (ICs). CMOS technology is used in microprocessors, microcontrollers, memory chips, and other digital logic circuits. CMOS circuits use both NMOS (n-type MOSFET) and PMOS (p-type MOSFET) transistors to implement logic functions. This complementary approach provides high noise immunity and low static power consumption. CMOS is commonly used in digital circuits due to its speed, low power consumption, and scaling capabilities.
