Abstract
A voltage controlled oscillator, includes a tank circuit including an inductor having a value L, interconnected with first and second variable capacitors, having values Cand C, and a fixed capacitor C, to cause oscillation of the oscillator at a controlled frequency Ccontrols coarse frequency tuning of the oscillator, and Cmay control fine tuning of the oscillator. The variable capacitors may be formed using accumulation-mode MOS varactors.
