Complementary Metal Oxide Semiconductor is a low power based semiconductor technology which is very popular in contemporary digital electronic devices like microprocessors, microcontrollers SRAMs etc. and also analog devices like image sensors and transceivers. A CMOS uses a symmetric pair of n-MOSFETs and p-MOSFETs as one functional entity to construct digital logic circuits. It offers features like high noise immunity and low static power dissipation which are two key factors in electronic design along with providing high density logic functions which makes it one of the most favored technologies in VLSI design.
