Ultra-low-power level shifter, voltage transform circuit and RFID tag including the same
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.
摘要（中）：

电平移位器通过采用电流欠压配置，以相对较低的功耗增加输出信号的电压电平。 电平移位器包括输入单元和驱动单元。 输入单元包括被配置为响应于输入信号和偏置电压产生控制信号的电流饥饿逆变器。 输入单元由第一电源电压供电。 驱动单元根据控制信号生成输出信号。 输出信号具有高于输入信号的电压电平，并且驱动单元由比第一电源电压高的第二电源电压供电。
