Component Specifications

Definition
Transmission gates/switches are solid-state electronic devices used in multiplexer circuits to selectively connect or disconnect signal paths. They function as bidirectional analog switches that can pass signals in both directions with minimal voltage drop and distortion. These components typically consist of complementary MOSFET pairs (CMOS configuration) that provide low on-resistance and high off-resistance, allowing precise control over signal routing in digital and analog multiplexing applications.
Working Principle
Transmission gates operate using complementary MOSFET pairs (one NMOS and one PMOS transistor connected in parallel). When both transistors are activated by complementary control signals, the switch closes, creating a low-resistance path for signals to pass through. When deactivated, the switch opens, creating high impedance that blocks signal transmission. This bidirectional operation allows signals to flow in either direction with minimal distortion.

Semiconductor materials (silicon, gallium arsenide), doped silicon substrates, silicon dioxide insulation layers, aluminum or copper interconnects, protective passivation layers (silicon nitride, polyimide).
