ABSTRACT:
A duty cycle comparator is described for comparing the duty cycles of two digital signals. The duty cycle comparator comprises a first controllable current source, a second controllable current source and a charge accumulation device. The comparator provides an output signal that is representative of the difference between the duty cycles independent of the frequency of the two digital signals.
