Multiple voltage amplitudes for an oscillator in a phase-locked loop may be selected to meet various design goals/criteria (e.g., frequency range of operation, jitter, power consumption, etc.). These multiple voltage amplitudes may be stored in a lookup table memory that relates frequency ranges to reference voltages. A reference voltage for a particular oscillator may then be selected and generated. A feedback loop may compare the amplitude output by the oscillator to the reference voltage and adjusts a bias current of the oscillator with the goal of substantially equalizing the oscillator output to the reference voltage.
