摘要： An integrated circuit distributed radio frequency oscillator comprises a semiconductor chip which includes a differential input transmission line, a differential output transmission line and, coupled in parallel between these transmission lines at spaced apart portions, a number of differential amplifier cells with adjustable delay. The output end of the output transmission line is coupled back to the input end of the input transmission line by a feedback link with a pair of on-chip capacitors. The delay introduced by the amplifier cells is variable in response to a tuning voltage applied to a differential tuning input, making the oscillator suitable for use as a distributed VCO in, e.g. a phase-locked loop circuit. The layout of the oscillator on a semiconductor chip includes the series-connected arrangement of the differential transmission lines in a rectilinear spiral path.

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.
