Abstract
A duty cycle tuning circuit and a method thereof are provided, in which the duty cycle tuning circuit includes multiple interpolation circuits, an edge detection circuit, and a delay chain. Each interpolation circuit receives multiple phase clocks, and interpolates an interpolation clock from two of the phase clocks. The phase clocks have the same frequency but different phases. The edge detection circuit is connected electrically to the delay chain, and generates an output clock according to an edge of the interpolation clock.
