Abstract

Improved circuit for tracking extended spectrum signals. This circuit incorporates a charge pump that drives the control input of the VCO, the said charge pump being composed of two current generators that feed or extract current in a capacitor, in such a way that the capacitor applies its voltage to the input of the VCO, converting the variations produced in its charge into voltage variations of the VCO and therefore into the frequency generated by the latter.
