Abstract
A PLL circuit includes: a charge pump; a voltage-controlled oscillator including an oscillation portion; and a voltage-converting circuit configured to convert a voltage from the charge pump and apply the converted voltage to the voltage-controlled oscillator. The power supply range supplied to the voltage-converting circuit is larger than the power supply range supplied to the oscillation portion of the voltage-controlled oscillator.
