CMOS

CMOS (Complementary Metal-Oxide-Semiconductor) is a semiconductor technology used for constructing integrated circuits, particularly microprocessors, memory chips, and digital logic circuits. It combines both p-type and n-type MOSFETs in a complementary and symmetrical way to create logic gates with very low power consumption and high noise immunity. This technology is the foundation for most modern digital electronics, including CPUs, GPUs, and mobile devices.

Also known as: Complementary Metal-Oxide-Semiconductor, CMOS Technology, CMOS Logic, CMOS Circuit, CMOS Chip

Why learn CMOS?

Developers should learn about CMOS technology when working on hardware design, embedded systems, or low-level programming to understand the physical basis of digital circuits and optimize for power efficiency. It's essential for roles in semiconductor engineering, VLSI design, and IoT device development where minimizing energy usage is critical. Knowledge of CMOS helps in debugging hardware-related software issues and designing systems with better performance and battery life.
