Abstract
A circuit comprising an oscillator configured to generate a periodic signal in response to (i) control signal and (ii) a current. The current may be varied independently of the control signal. In one example, the oscillator may generate the periodic signal in further response to a second current that may vary in response to the control signal. In another example, the oscillator may be used in a phase-locked loop circuit.
