CMOS, or Complementary Metal-Oxide-Semiconductor, is a technology used in the manufacturing of electronic circuits, particularly in microprocessors, memory chips, and image sensors. It is known for its low power consumption and high noise immunity, making it ideal for battery-operated devices. CMOS technology utilizes both p-type and n-type transistors to create logic functions. This complementary arrangement allows for efficient operation, as one type of transistor turns off while the other turns on, reducing power usage. CMOS is widely used in various applications, including digital cameras and smartphones.
