A timer including a Pulse Width Modulation (PWM) signal generator configured to generate, based on a clock, a PWM signal having a first frequency resolution; a PWM time shifter configured to receive from the PWM signal generator the PWM signal having the first frequency resolution, and output a PWM signal having a second frequency resolution, wherein the second frequency resolution is higher than the first frequency resolution; and a control monitor configured to: control the PWM time shifter to time shift rising edges or falling edges of the PWM signal by an amount corresponding with a second frequency resolution.
