Abstract
A voltage controlled oscillator (VCO) which can be configured with a smaller tuning range than is ordinarily required is presented. Ordinarily, the tuning range is selected much broader than the application warrants so that sufficient range is still provided despite VCO process variations. The inventive VCO is able to substantially eliminate the effects of process variation by utilizing a calibration circuit and process, so that variation in VCO device operation is minimized despite substantial process variation. Accordingly, the inventive VCO device is subject to reduced levels of jitter as its range need not be utilized for overcoming process variation arising during device fabrication.
