Abstract
In a voltage-controlled oscillation circuit, a parallel resonance circuit which is formed by connecting a coil (an inductive element) and a capacitor (a capacitive element) in parallel with each other is provided between a control terminal and a resonance circuit. A control voltage is inputted at the control terminal and is supplied to the resonance circuit through the parallel resonance circuit, so that the resonance frequency of the resonance circuit is responsive to the control voltage; an oscillation stage of the voltage-controlled oscillation circuit oscillates at that resonance frequency. The oscillation output of the oscillation stage is outputted at an output terminal from a buffer stage through an output matching stage.
