Transmission gate

A transmission gate is a electronic element, representing an ideal non-mechanical relay, built with CMOS technology.

Probably more usually known as an analog gate or electronic relay dependent on use.

A current can flow through this element in either direction. Depending on whether or not there is a voltage on the gate, the connection between the input and output is either low-resistance or high-resistance, respectively.

Ron = 100 ohm and Roff > 5 megohm.

A basic CMOS transmission gate consists of NMOS and PMOS.
