Abstract

This is a circuit for shifting the phase of a signal by 90 degrees to provide timing information in applications such as fast power-loss detection. The circuit provides a logic output waveform with transitions centered on input pulse periods corresponding to a 90 degree phase shift of a squarewave input.
