A circuit for providing voltage level shifting in an integrated circuit includes an inverter (610) having an input coupled to receive an input signal having a first voltage level (VDDL); an output stage (618) having a first transistor (620) coupled in series with a second transistor (622), and an output node (660) between the first transistor and the second transistor generating an output signal (OUT) having a second voltage level (VDDH). A gate (622) of the second transistor is coupled to an output (616) of the inverter. A pull-up transistor (630) is coupled between a reference voltage (VDDH) having the second voltage level and a gate (649) of the first transistor. A switch (624) is coupled between the gate of the first transistor and the gate of the second transistor to control a voltage at the gate of the first transistor. A method of providing voltage level shifting in an integrated circuit is also disclosed. 种用于在集成电路中提供电压电平移位的电路，其包括：反相器(610)，其具有被耦接来接收具有第电压电平(VDDL)的输入信号；输出级(618)，其具有与第二晶体管(622)串联耦接的第晶体管(62
