Abstract
A frequency-generator circuit employs the same circuit element (preferably a varactor) to perform the functions of parametric frequency-divider and frequency-adjustment element for an oscillator used to pump the parametric frequency-divider. The varactor preferably has a flat gamma-characteristic (gamma preferably >2) over a required bias-voltage adjustment range corresponding to the required frequency-adjustment range.
