摘要：
According to an embodiment, a voltage-controlled oscillator has a variable capacitive element with a capacitance that is changed by a voltage to be applied thereto. One electrode of the variable capacitive element is connected to a control input terminal where a control voltage that controls an oscillation frequency is applied thereto. It has a compensation voltage generation circuit that generates a voltage that changes with a temperature thereof. It has a resistive element with one end that is directly connected to another electrode of the variable capacitive element and another end that is supplied with an output voltage of the compensation voltage generation circuit.
