Abstract

An apparatus for oscillating a frequency, which comprises a phase lock loop, see fig. 5, a variable frequency divider() is shown, that divides a first frequency (Fout) signal by a division ratio to generate a second frequency signal, this based on a comparison of reference frequency clock input (Fref) and feedback input to phase/frequency detector (510). A charge pump (520) and loop filter (530) are shown with a divider (550) that divides the second frequency signal (355) to allow the correct feedback frequency to be realized. The VCO (540) inherently has a resonant circuit including the capacitors to be selected and a corresponding control voltage to set the frequency of operation as well as an active circuit (320) for proper gain.
