Abstract
An LC-type oscillator employing a differential amplifier to switch a tank circuit in response to a feedback signal. A voltage controlled variable capacitor is employed to control the frequency of oscillation. The bias across the variable capacitor is closely controlled to avoid errors in the frequency of oscillation during the period of startup, which would otherwise create an undesired error in the oscillation frequency.
