ABSTRACT:
A phase shift driver for phase shifting an input clock signal at a first phase to generate an output signal at a second phase without missing subsequent input signals. Input logic circuitry of the phase shift driver may receive an input signal at a first phase. Output logic circuitry of the phase shift driver may generate an output signal at a second phase relative to the input signal. The output signal may be a phase-shifted version of the input signal. A reset control circuit may receive a feedback signal from the output logic circuitry and an intermediate signal from the input logic circuitry and generate a reset signal based on the received feedback and intermediate signals. The reset control circuit may control a pulse width of the reset signal to reset the input logic circuitry within a period of time before the input logic circuitry receives a subsequent input signal.
