ABSTRACT:
A PLL can operate linearly at various frequencies by overlapping several VCOs and using a control circuit for controlling the several VCOs to select a VCO at a desired frequency. Accordingly, the PLL can automatically pre-compensate the frequency by using a control signal used in the PLL. As a result, a separate frequency compensation signal is not required. The PLL can be configure on a single chip when the VCO is contained within the PLL.
