摘要： An LC tank circuit, such as an LC tank circuit of a step-tuned voltage controlled oscillator, includes a plurality of switched capacitor banks and one or more inductors. A first switched capacitor bank switch in response to a range of control signals used to control the VCO output across a range of frequencies. A second switched capacitor bank can switch in response to a subset of the range of control signals used to control the VCO output across a subset of the range of frequencies. The control scheme for the first and second switched capacitor banks can improves the linearity of changes in the frequency of the output signal of the VCO.

摘要： An end-open stub (4) having a line length equivalent to a quarter wavelength of an oscillation frequency F0 multiplied by 2N, i.e., a frequency 2N F0 is connected to a collector terminal of a transistor (1) while an output terminal (6) is arranged at the connection point (5) between the collector terminal of the transistor (1) and the end-open stub (4). An end-open stub (7) having a line length longer than the quarter wavelength of the signal of the oscillation frequency F0 is connected to a base terminal of the transistor (1) while an output terminal (9) is arranged at the connection point (8) located at a position equivalent to a quarter wavelength of the signal of the oscillation frequency F0 from the tip end of the end-open stub (7).

摘要： An integrated circuit distributed radio frequency oscillator comprises a semiconductor chip which includes a differential input transmission line (14), a differential output transmission line (16) and, coupled in parallel between these transmission lines at spaced apart portions, a number of differential amplifier cells (18-1, 18-2, 18-3, 18-4) with adjustable delay. The output end of the output transmission line (16) is coupled back to the input end of the input transmission line (14) by a feedback link (20) with a pair of on-chip capacitors (22A, 22B). The delay introduced by the amplifier cells (18-1, 18-2, 18-3, 18-4) is variable in response to a tuning voltage applied to a differential tuning input (30), 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 (14, 16) in a rectilinear spiral path.

摘要： 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.
