摘要： A level shifter increase a voltage level of an output signal with relatively lower power consumption by adopting current-starved configuration. The level shifter includes an input unit and a driving unit. The input unit includes a current-starved inverter configured to generate a control signal in response to an input signal and a bias voltage. The input unit is powered by a first power supply voltage. The driving unit generates an output signal in response to the control signal. The output signal has a voltage level higher than the input signal, and the driving unit is powered by a second power supply voltage higher than the first power supply voltage.
