Abstract
Systems and methods for increasing Pulse Width Modulation (PWM) resolution for digitally controlled motor control applications are described. For example, in some embodiments, a method may include receiving a clock signal having a given period; identifying a target duty cycle; calculating a comparison point based upon the given period and the target duty cycle; generating a PWM signal based upon the clock signal using the comparison point; and varying the comparison point to increase a resolution of an effective duty cycle of the PWM signal.
