High-speed divider with pulse-width control

An apparatus for dividing a first signal having a first frequency by a divide ratio to generate a lower frequency signal comprising:

• a pulse-width control circuit responsive to at least one signal having a first pulse width and configured to generate a first plurality of signals having a common frequency, a second pulse width based, at least in part, on the divide ratio, and respective ones of different phases;
• and
• a select circuit configured to receive the first plurality of signals and to supply a first selected signal of the first plurality of signals as a select circuit output signal according to a select signal.

An apparatus for dividing a first signal having a first frequency by a divide ratio to generate a lower frequency signal comprising:

• means for generating a first plurality of signals having a common frequency, a first pulse width, and different phases, the first plurality of signals being based, at least in part, on at least one signal having a second pulse width, the first pulse width being selected from a plurality of pulse widths based, at least in part, on the divide ratio;
• and
• means for sequentially selecting individual pulses of the first plurality of signals as an output signal of the sequentially selecting means to generate an output signal having a frequency lower than the first frequency.
