ABSTRACT:
A transmission gate includes first and second MOS transistors of opposite conductivity type coupled in parallel with each other. Each transistor includes a body connection that is separately biased by corresponding first and second biasing circuits. The first biasing circuit generates a first bias voltage having a voltage level that is generated as a function of the signal at the first node and a first (for example, positive) reference voltage. The second biasing circuit generates a second bias voltage having a voltage level that is generated as a function of the signal at the first node and a second (for examples ground) reference voltage.
