Complementary Metal-Oxide-Semiconductor, or CMOS, is a technology used in the manufacturing of electronic circuits, particularly in microprocessors, memory chips, and image sensors. It utilizes complementary pairs of p-type and n-type transistors to perform various functions, allowing for low power consumption and high noise immunity. CMOS technology is widely favored in modern electronics due to its efficiency and scalability. It enables the integration of millions of transistors on a single chip, making it essential for devices like smartphones, computers, and digital cameras. The ability to operate at low voltages further enhances its appeal in portable electronics.
