| Summary: | A control voltage is fed to an oscillation circuit from a control terminal, and a power supply voltage is fed thereto from a power supply terminal. An output circuit is provided between the oscillation circuit and an output terminal. The power supply terminal is connected to a feedback terminal through a DC separating capacitor and an amplifier. A signal leaking out to the power supply terminal from the oscillation circuit is fed to the amplifier through the DC separating capacitor. The amplifier amplifies the signal leaking out to the power supply terminal, and feeds the amplified signal to the feedback terminal as a feedback signal Loop. |
