Complementary Logic

Complementary logic is a design approach used in digital electronics, especially in creating logic gates like NOT, AND, and OR. It involves using pairs of transistors—specifically, one n-type and one p-type—to efficiently switch signals on or off. This arrangement allows for lower power consumption and faster operation because, at any given time, only one transistor in the pair conducts, reducing unnecessary current flow. In essence, complementary logic provides a reliable and energy-efficient way to process binary signals (0s and 1s) in digital devices.
