Abstract

In accordance with an embodiment, a method of operating a voltage controlled oscillator (VCO) that having a VCO core coupled to a filtered current source includes setting an oscillation frequency of the VCO core based on a tuning signal received at a tuning signal input; and setting a resonant frequency of the filtered current source based on the received tuning signal using a tuning circuit having an input directly connected to the tuning signal input.
