Abstract
A driving device is provided for controlling rotation of a motor. The driving device comprises an inputting module, a comparing module and a processing module. The inputting module includes a first current source, a first voltage source and a first capacitance. The first capacitance is coupled between the first current source and the first voltage source for charging/discharging and generating a voltage signal. The comparing module is coupled to the inputting module for comparing a selecting signal with the voltage signal and generating a comparing signal. The processing module is coupled to the comparing module and generates a control signal according to a clock signal and the comparing signal, wherein the driving device controls the rotation of the motor by the control signal.
