摘要： A voltage controlled oscillator which performs an oscillating operation at a frequency corresponding to a control voltage, includes a voltage-current converter circuit which converts the control voltage to a control current corresponding to a voltage value thereof, and a ring oscillator through which an operating current corresponding to the control current generated by the voltage-current converter circuit is caused to flow, and which oscillates at a frequency corresponding to a current value thereof. The voltage-current converter circuit has a voltage-voltage converting circuit which inputs the control voltage therein and converts the same to a control current corresponding to the voltage value thereof, and an offset current generating circuit which adds a constant current to the control current.
