Pulse width modulation (PWM) is a very common technique used in different applications, from the control of motors, switching power converters (power supplies), audio amplifiers or illumination systems. In some of those applications, the pulse frequency has increased so much in the last years that the resolution obtained with classical (counter) techniques is not enough. This paper explains some methods used for increasing the resolution of PWMs and proposes a new method based on the resources available in almost every FPGA nowadays.
