<p>A differential frequency divider includes first and second input terminals each configured to receive a differential input signal. The divider also includes a first output terminal configured to produce a first output signal and a second output terminal configured to produce a second output signal. The divider further includes a third input terminal coupled to the first output terminal and a fourth input terminal coupled to the second output terminal. In addition, the divider includes a first variable current source. Altering a current of the first variable current source causes a change in the phase difference between a first output signal of the first output terminal and a second output signal of the second output terminal.</p>
