    Abstract: An integrated circuit (IC) includes a substrate and a first capacitor on the substrate. The first capacitor has a first width. A first dielectric layer is provided on a side of the first capacitor opposite the substrate. Further, a second capacitor is present on a side of the first dielectric layer opposite the first capacitor. The second capacitor has a second width that is smaller than the first width. The IC also has a second dielectric layer and a first metal layer. The second dielectric layer is on a side of the second capacitor opposite the first dielectric layer. The first metal layer is on a side of the second dielectric layer opposite the second capacitor.

    Abstract: A variable capacitor is provided such that it is possible to make nonlinear distortion small and use at high power handling capability, and such that a variable rate of capacitace is not influenced by a high-frequency voltage substantially. A variable capacitor is used by changing capacitance through application across electrodes of direct current voltage and high-frequency voltage. When an effective voltage value of high-frequency voltage is within a rage of voltage values of direct current voltage, there is substantially no fluctuation caused by application of high-frequency voltage with respect to a change of capacitance caused by application of direct current. Since it is possible to decrease susceptibility to the high-frequency voltage of the variable capacitor, it is possible to obtain a variable capacitor such that nonlinear distortion is small and power handling capability is high.

    Abstract: A variable capacitor is provided. The variable capacitor includes a plurality of capacitor segments. The plurality of capacitor segments are connected in parallel within the variable capacitor. When a plurality of candidate capacitances allowable to the variable capacitor according to a connection state of the plurality of capacitor segments connected in parallel are sorted in a magnitude sequence, the plurality of candidate capacitances form a geometric series. The variable capacitor is used for a Voltage Controlled Oscillator (VCO), and the VCO is used for a Phase Locked Loop (PLL).
