Abstract
A voltage provision circuit includes a first NMOS transistor gated with a first control signal and sourced with a ground voltage, a second NMOS transistor gated with a second control signal complementary to the first control signal and sourced with the ground voltage, a first PMOS transistor sourced with a first supply voltage, a second PMOS transistor sourced with the first supply voltage, and a voltage modulation circuit that is coupled between the first to second PMOS transistors and the first to second NMOS transistors, and is configured to provide a first intermediate signal based on the first and second control signals. The first intermediate signal has a first logic state corresponding to the first supply voltage and a second logic state corresponding to a second supply voltage that is a fraction of the first supply voltage.
