Abstract
A voltage control oscillator includes: a voltage-current converter circuit that converts an inputted voltage to a current according to the value of the voltage; a current mirror circuit; a ring oscillator including differential inverters connected in multiple stages; an inverting amplifier; and a buffer. The ring oscillator outputs, from each of the differential inverters, a signal amplitude-limited by a current converted by the voltage-current converter circuit and the current mirror circuit and a voltage applied from the inverting amplifier and the ring oscillator outputs an oscillatory frequency in response to the output signal.
