Abstract
A phase shift generation circuit has an edge detector, which outputs a first and a second edge signal. The circuit also has a divide by N circuit, which receives a first clock signal and a group of signals representing a number N, and outputs a second clock signal. The circuit further comprises a pulse counter, which receives the first edge signal and the second clock signal, and outputs a group of signals representing the number of the second clock pulses between occurrences of the first edge signal. The circuit has first and second recycling timers, which output a group of pulses approximating a uniformly spaced group across the time duration of the period of the input pulse. The circuit also comprises at least one flip flop which generates a phase shifted output pulse.
