ABSTRACT:
A system and method for providing, among other things, wideband phase modulation is described. Several embodiments include a scaling network for scaling an input modulation signal in accordance with a scaling parameter and thereby generating a scaled modulation signal that is applied to a voltage-controlled oscillator of a phase-locked loop. A sensing network may also be included for detecting changes in one or more parameters characterizing the voltage-controlled oscillator. A calibration adjustment network may additionally be included for adjusting the scaling parameter in accordance with the changes in the one or more parameters.
