Abstract
The present invention provides a circuitry applied to multiple power domains. An amplifier of the circuitry includes an output stage and a switching circuit. The output stage includes a first transistor and a second transistor, wherein the first transistor is coupled between a supply voltage and an output terminal, the second transistor is coupled between the output terminal and a ground voltage. The switching circuit is configured to choose a body of the first transistor from the supply voltage or a reference voltage.
