Abstract
A circuit includes a power management circuit configured to receive at least a first or a second control signal, and to supply at least a first, second or a third supply voltage. The first control signal has a first voltage swing. The second control signal has a second voltage swing. The power management circuit includes a first level shifter circuit configured to generate a first level shifted signal in response to the first control signal, and a first header circuit coupled to at least the first level shifter circuit, a first voltage supply and a second voltage supply. The first header circuit is configured to supply the first supply voltage of the first voltage supply to the first node in response to the first control signal, and to supply the second supply voltage of the second voltage supply to the second node in response to the first level shifted signal.
