Abstract
A voltage-controlled oscillator including a voltage-controlled oscillation section, a frequency control bias circuit, a temperature compensation bias circuit, and a temperature compensation bias generation circuit. The temperature compensation bias generation circuit has a transistor having its collector or drain connected to the temperature compensation bias circuit, a first resistor having one end connected to the collector or drain of the transistor and having another end that is grounded, a second resistor having one end connected to the base or gate of the transistor, a base or gate bias application terminal connected to another end of the second resistor, a third resistor having one end connected to the emitter or source of the transistor, and an emitter or source bias application terminal connected to another end of the third resistor.
