    摘要: A pulse-width control loop (PWCL) for clock with any pulse-width ratio within a wide range is provided. A differential programmable charge pump is employed to stabilize the current source by complementary connection. The differential programmable charge pump has a pair of differential charge pumps and a current source module to adjust the ratio of charge to discharge, so as to accelerate the range of the adjustable pulse-width ratio of the output clock and increase the output resolution. Further, a ratioless input control stage is employed to simplify the circuit design and avoid static power consumption. Moreover, the control stage adjusts rising pulse width and dropping pulse width at one period, thereby accelerating the lock speed and the range of the adjustable pulse-width ratio (i.e., duty cycle) of the input clock.

The value generation unit outputs a counting value. The accumulating unit accumulates the counting value to output a waveform value. The accumulating unit switches from an increasing mode to a decreasing mode if the waveform value is a third boundary value, and the accumulating unit switches from the decreasing mode to the increasing mode if the waveform value is a fourth boundary value.
