An aspect of the present invention is a voltage controlled oscillator that provides multi octave band tenability. The oscillator preferably includes one or more multi planar resonators which allow it to be implemented in integrated circuit form. Oscillators implemented in accordance with the aspect of the present invention provide as wide a tuning range as the YIG based resonators but are much more compact and efficient. Therefore, they are amenable to implementation in integrated circuits and suited for adaptation in third and future generation wireless devices.

User-definable low cost, low noise, and phase hit insensitive multi-octave-band tunable oscillator

A tunable oscillator includes a first transistor, a second transistor connected in parallel with the first transistor, a noise feedback and bias network coupled to the first and second transistors, a planar coupled resonator network coupled to the transistors and a means for dynamically tuning the resonant frequency of the planar coupled network and the junction capacitance of the transistors.

User-definable, low cost, low phase hit and spectrally pure tunable oscillator

An oscillator comprising an active device having first, second and third terminals, a plurality of micro-stripline resonators coupled together to form a coupled-resonator network, the coupled-resonator network being coupled to the second terminal of the active device and a tuning network coupled to the coupled-resonator network, the tuning network being operable to adjust the coupling between at least two of the resonators that form the coupled resonator network.

Low noise, hybrid tuned wideband voltage controlled oscillator

A voltage controlled oscillator that includes a slot-cut-microstrip-line coupled between a resonator, a tuning diode network and an active device and being operable to act as a common-coupling capacitor between the resonator, the tuning diode network and the active device.

User-definable thermal drift voltage control oscillator

An oscillator comprising a cascode configured device having first, second and third terminals, a plurality of resonators and first circuitry coupled between the plurality of resonators and the second terminal of the cascode configured device. The first circuitry is preferably operable as an evanescent mode buffer to compensate for changes in the capacitance of the oscillator during operation.
