Abstract
An offset related to a feedback system for a VCO is quantified and then a parameter of the feedback system is adjusted in response to the quantified offset to correct for the offset. Correcting for offset in a feedback system can improve the performance of a PLL by reducing phase drift between the input signal and the VCO signal. The reduced phase drift can have benefits such as, for example, reduced bit errors and/or improved phase tracking accuracy.
