Abstract
The present disclosure describes a power supply switch that includes a voltage generator, a switch circuit, and a confirmation circuit. The voltage generator is configured to compare a first power supply voltage to a second power supply voltage and to output the first power supply voltage or the second power supply voltage as a bulk voltage (Vbulk). The switch circuit includes one or more transistors and is configured to (i) bias bulk terminals of the one or more transistors with the Vbulk and (ii) output either the first power supply voltage or the second power supply voltage as a voltage output signal. The confirmation circuit is configured to output a confirmation signal that indicates whether the voltage output signal transitioned from the first power supply voltage to the second power supply voltage.
