CHMOS

CHMOS stands for Complementary Metal-Oxide-Semiconductor. It is a type of semiconductor technology used in the design and fabrication of integrated circuits, particularly microprocessors and microcontrollers. The key feature of CHMOS technology is its use of both P-channel and N-channel metal-oxide-semiconductor field-effect transistors (MOSFETs) to create complementary circuits. This pairing allows for very low static power consumption because in any given state, at least one of the transistors in a complementary pair is in a high-impedance state, effectively turning off.

This low power characteristic makes CHMOS widely adopted in battery-powered devices and applications where energy efficiency is critical. The development of CHMOS has been a significant factor in the miniaturization and increased performance of electronic devices over several decades. It enabled the creation of more complex and powerful chips while managing heat dissipation and battery life. CHMOS technology is a fundamental building block in modern digital electronics, forming the basis for the vast majority of integrated circuits found in computers, smartphones, and countless other electronic gadgets.
