摘要： A broad oscillation frequency range and good phase noise characteristic are achievable simultaneously by an oscillation circuit and a resonance circuit connected to the oscillation circuit. The resonance circuit includes an inductor element connected to the oscillation circuit, a first variable capacitance section connected to the inductor element, and a second variable capacitance section connected in parallel to the first variable capacitance section. The first variable capacitance section includes a first variable capacitive element connected to the inductor element, and a second variable capacitive element connected in parallel to the first variable capacitive element. The first variable capacitive element changes its capacity value based on a control voltage and a first reference voltage. The second variable capacitive element changes its capacity value based on the control voltage and a second reference voltage. The first reference voltage and the second reference voltage are controlled based on the capacity value of the second variable capacitance section.
