Abstract
Circuits and methods for providing an accurate phase shift between a generated output signal and an input signal are disclosed. The circuits and methods enable any amount of accurate phase shift to be set without requiring significant changes in circuitry with each phase shift. The phase shift is set by a voltage applied to a feedback amplifier connected to a low-pass filter and a timer circuit that resets a latch circuit.
