PURPOSE: The pulse generator of a positioning module is provided to reduce the generation of vibrations and noises, and a step-out phenomenon in a vibrator by generating a pulse signal with a frequency which is less than decimal points. CONSTITUTION: A load signal generating unit(400) generates a load signal when a pre-set controlling cycle is terminated. The load signal generating unit includes a controlling cycle buffer(402) and a first comparator(404). A reference clock signal count unit(410) counts a reference clock signal from a pre-set frequency value when the load signal is generated. A phase change signal generator(420) compares the counted value of the reference clock signal count unit and a pre-set reference value. A pulse signal outputting unit(430) outputs a pulse signal according to a phase change signal generated from the phase change signal generator. |
