Abstract
In one embodiment, an apparatus includes: a bias circuit having a replica circuit, the bias circuit to generate an oscillator current that is proportional to a variation of the replica circuit; an oscillator circuit coupled to the bias circuit to receive the oscillator current and generate a plurality of signals using the oscillator current; and a waveform shaper circuit coupled to the oscillator circuit to receive the plurality of signals and generate at least one clock signal from the plurality of signals.
