Abstract

A VCO device is described that has pre-compensation. Digitally switchable compensation capacitors are selectively activated to adjust operation of the VCO to mitigate undesirable operational effects. In some example embodiments, the digitally switchable compensation capacitors of the VCO are adjusted to compensate for the effects of activating (from a quiescent state) an output buffer driven by the VCO.
