ABSTRACT:
A differential oscillator circuit, including an oscillator having a first side and a second side and bias circuitry for applying a bias voltage to the first and second sides of the oscillator wherein the bias circuitry is arranged such that, upon start-up, the bias voltage is not applied to the second side of the oscillator until after the first side of the oscillator by a delay period.
