Abstract
A division factor generator of a feedback divider block in a fractional-N phase locked loop (PLL). The division factor generator is enabled to operate with larger values of division factors without increased complexity of an internal modulator core implemented, for example, as a delta-sigma modulator (DSM) having a signal transfer function (STF), wherein the STF always generates only an integer value as an output in response to an integer value received as input.
