Abstract
Systems, methods, and devices are described herein for generating a pulse width modulation (PWM) signal having a specific duty cycle. In one embodiment, the system includes a square wave generator and a logic device. The square wave generator is configured to delay a input square wave signal to generate a plurality of square wave signals. The logic device is configured to perform a logic operation to two of square wave signals of the plurality of square wave signals, which in turn generates the PWM signal having a duty cycle corresponding to the two square wave signals.
