A circuit architecture, or topology, that provides a level shifter which is substantially independent of the duty cycle of an input signal includes an H-bridge arrangement of field effect transistors, a pair of capacitively coupled inputs terminals connected to the gates of the high-side (i.e., connected to the positive power supply) transistors and a pair of voltage dividers to set the bias voltage at the gates of the high- side transistors, wherein one side of each voltage divider is coupled to the power supply node and the other side of each voltage divider is cross-coupled to the output node of the opposite side of the H-bridge.
