Abstract
A logic circuit includes a logic gate unit, an inverter, and a switching circuit. The logic gate unit receives a power supply voltage and an input signal to output a first signal. The inverter receives the first signal to output a second signal. The switching circuit provides one of first and second power supply voltages as the power supply voltage of the logic gate unit in response to the first and second signals. The first power supply voltage and the second power supply voltage have different voltage levels, thus enabling stable level shifting.
