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).

Claim (Index 15):
A phase locked loop (PLL) comprising:\n a phase comparator configured to measure a phase difference between a phase of an input signal and a phase of a signal fed back from a voltage controlled oscillator (VCO) and to output a voltage signal proportional to the phase difference; and a low pass filter configured to remove a high frequency component of the voltage signal and to output a control voltage, wherein the VCO is configured to generate an output signal with a frequency according to a control code corresponding to the control voltage, wherein the VCO comprises a variable capacitor configured to provide one of candidate capacitances, wherein the variable capacitor comprises a capacitor bank comprising a plurality of capacitor segments, and a plurality of switch segments configured to control connection states of each of the plurality of capacitor segments, wherein the capacitor bank provides one of candidate capacitances based on connection states of capacitor segments, wherein the connection states are controlled based on a control code, wherein a capacitance provided from the capacitor bank is linearly changed on a log scale by linearly increasing a value of the control code, and wherein the frequency of the output signal is linearly changed on the log scale by linearly increasing the value of the control code.
