Standard Functional Configurations for Analog Switches and Multiplexers

The function of any switch is to either connect or isolate two sections of a circuit. A simple light switch performs this function with direct, manual, mechanical control over the electrical connection from the power line to the light bulb. A relay provides indirect control of an electrical connection, replacing the manual control of the connection with remote electrical control of the switching action. An analog switch is like a relay, but the mechanical control of the connection is replaced by an electronic switch, such as a Field Effect Transistor (FET). The switching action in an analog switch is provided by a logic input that is compatible with standard logic interface standards, such as TTL.

A transmission gate (Figure 1(a)), or analogue switch, is defined as an electronic element that selectively blocks or passes a signal level from the input to the output. Also, it is known that an nFET and pFET cannot pass a strong logic 1 and logic 0 voltages, respectively [1]. So, by connecting the two devices in parallel, the full voltage range from 0 V to VDD can be transmitted.
