Abstract:
In one embodiment, the digital pulse width modulator of these teachings includes comparators and a number of phases and capable of increasing resolution without increasing clock frequency. In another embodiment, the digital pulse width modulator (DPWM) of these teachings includes equality comparators and a number of phases and increases resolution without increasing clock frequency. A further embodiment of the system of these teachings includes a priority encoded comparator component (in one instance including a number of comparators) comparing duty cycle commands against preset minimums, that embodiment being referred to as a frequency Foldback component. Other embodiments and embodiments of the method of these teachings are also disclosed.
