Abstract
A level shifting circuit receives a first input signal and complement of the first input signal as inputs and generates a level shifted first output signal and complement of the first output signal as outputs. The level shifting circuit includes a number of transistors that support body biasing. One set of body bias signals applied to certain ones of those transistors is generated as a function of the logical combination of the first input signal and the first output signal. Another set of body bias signals applied to certain other ones of those transistors is generated as a function of the logical combination of the complement of the first input signal and the complement of the first output signal. The conditional body bias applied to the transistors of the level shifting circuit makes the circuit operational for level shift at very low supply voltage levels.
