ABSTRACT:
A voltage controlled oscillator comprises more than one dissimilar diode. The dissimilar diodes have different capacitance versus voltage characteristic shapes. The dissimilarity causes the tuning gain factor of the resulting oscillator to be an increasing function of increasing frequency. Such an oscillator when properly incorporated into a phase lock loop can yield loop parameters which are a constant function of increasing frequency.
