Abstract: Provided are a differential voltage-controlled oscillator (VCO) and a quadrature VCO using center-tapped cross-coupling of a transformer. The differential VCO and the quadrature VCO can be driven by low power through a current reuse structure and have an excellent phase noise characteristic by center-tapped cross-coupling through a transformer. Further, variable capacitance units for frequency variation are divided into variable capacitance units for coarse tuning and variable capacitance units for fine tuning. Therefore, it is possible to obtain a wide tuning range while voltage oscillation gain is reduced. Further, the differential VCO and the quadrature VCO are configured in such a manner that the respective variable capacitance units operate linearly throughout the entire capacitance region due to control voltage distribution by resistors. Accordingly, it is possible to obtain a linear control voltage-oscillation frequency characteristic. The quadrature VCO according to the present invention can output four-phase quadrature signals while having an excellent phase noise characteristic, without substrate loss and current consumption caused by the switching transistors.

In the CPW including an interlayer insulator disposed on a substrate, metal multilayers disposed on the interlayer insulator, and a ground line-a signal line-a ground line formed of an uppermost metal layer, when a ground line of a lowermost layer is connected to the ground line of the uppermost layer, intermediate metal layers are designed to gradually increase or decrease in width, or to be uneven so as to maximize an area where an ultra-high frequency spreads, thereby minimizing CPW loss and maximizing a slow wave effect. As a result, it is possible to improve performance of an ultra-high frequency circuit and miniaturize the circuit.
