Abstract
A power switch circuit includes a first transistor, a second transistor and a current source. A first source/drain terminal and a gate terminal of the first transistor receive a first supply voltage and a second supply voltage, respectively. A second source/drain terminal and a body terminal of the first transistor are connected with a node z. An output signal is outputted from the node z. A first source/drain terminal and a gate terminal of the second transistor receive the second supply voltage and the first supply voltage, respectively. A second source/drain terminal and a body terminal of the second transistor are connected with the node z. The current source is connected between a bias voltage and the node z. The first supply voltage, the second supply voltage or the bias voltage is selected as the output signal.
