Abstract
An apparatus and method for multiplying frequency of a clock signal are provided, wherein the apparatus provides an initial oscillator signal, compares the initial oscillator signal with a reference signal to generate a first control signal, selectively outputs one of at least one lower threshold value and at least one upper threshold value from a threshold value generation circuit to a clock output circuit according to at least the first control signal, and updates an output clock signal through a digital and logical module processing the comparison of the initial oscillator signal and the selected one of the at least one upper and lower threshold values and the comparison of the initial oscillator signal and a low level signal.
