摘要： The voltage-controlled oscillator can include a voltage-current conversion circuit that outputs a control current corresponding to the control voltage, and a ring oscillator that generates an output signal with a frequency corresponding to the control current. According to an embodiment, by using a voltage-current conversion circuit, it is possible to design a voltage-controlled oscillator that can operate even with a relatively low supply power and have stable characteristics even when the temperature changes.
