Disclosed herein is a method and apparatus used to create an idealized voltage controlled oscillator (VCO) which allows very high modulation rates without the expected phase noise (jitter) which nominally comes from wide bandwidth VCOs. In this fashion, high quality VCOs that typically offer pure signals at the cost of small tuning bandwidths can be enhanced to create idealized VCOs that offer both high quality (low jitter) and high tuning bandwidths. A high-frequency phase modulator and control voltage processing is used in conjunction with a natural VCO to create a method and apparatus in accordance with the invention. The control voltage processing includes separation of frequency components of the controlling voltage and electrical integration of high-frequency control voltage components directed to the phase modulator to create the overall voltage-to-frequency transfer function for the ideal VCO.
