Abstract
A level shifter that shifts a voltage level of an input signal, where the input signal oscillates between a voltage level of a first supply voltage and ground. The level shifter includes a bias circuit, and first and second transistors. The bias circuit provides a bias voltage to the first transistor based on the first supply voltage. The second transistor is connected in series with the first transistor, and the series combination is connected between voltage supplies that provide second and third supply voltages. The second transistor receives the input signal at its gate, and a level-shifted version of the input signal is output at a node between the first and second transistors. The level-shifted signal oscillates between the voltage levels of the second and third supply voltages.
