Abstract
Voltage-controlled oscillator with apparatus for automatic calibration. The voltage-controlled oscillator includes switches connecting associated coarse-tuning capacitors to an LC resonant tank of the oscillator. The voltage-controlled oscillator also comprises a calibration loop used to appropriately set the switches associated with the coarse tuning apparatus based on a oscillator control signal.
