Abstract
A shifter receives a multi-logic state input signal and generates a multi-logic state output signal responsive to switches in logic state of the input signal and whose voltage level is shifted with respect to the input signal. A feedback circuit feeds a signal derived from the output signal back to the shifter to precondition the shifter so that the speed of the output signal switching is accelerated.
