Abstract:
1. A voltage controlled oscillator, comprising: a first device having first, second and third terminals; a second device having first, second and third terminals, the first device and second device being coupled in a push-push configuration; circuitry for a tunable phase coupling network coupled between respective first terminals of the first device and the second device, the circuitry comprising at least two diodes; circuitry comprising one or more tunable coupled resonator networks coupled to the third terminals of each of the devices through a tuning voltage network; and a dynamically tuned combiner network coupled between respective first terminals of the first and second devices, wherein the voltage of the tuning network can be adjusted to tune a frequency of an output signal generated by said dynamically tuned combiner network over at least an octave frequency band.
