Abstract
Certain aspects of the present disclosure provide apparatus for producing an output signal having a duty cycle of 50% and a frequency that is one third that of an input signal. One example frequency dividing circuit for producing such an output signal generally includes first and second flip-flops; first, second, and third logic circuits, each configured to function equivalently to a logic OR gate; and an internal frequency dividing circuit configured to generate an output waveform having a frequency that is one half that of an input waveform.
