Voltage control type oscillator

A voltage control type oscillator comprising:

• a resonance circuit including a parallel resonance circuit;
• and
• an oscillation stage wherein an oscillation frequency of said oscillation stage varies within a predetermined frequency band by varying a resonance frequency of the parallel resonance circuit of said resonance circuit on the basis of an inputted control voltage, said oscillation stage including:
• an active element having a current output terminal and adapted to compensate for a power loss in said parallel resonance circuit;
• a bias resistor for regulating the DC bias of the current output terminal of said active element;
• a strip line connected in series with said bias resistor, said strip line having an inductance larger than that of said bias resistor within a predetermined frequency band;
• and
• a chip capacitor which is connected in parallel to said strip line and whose capacitance value is determined so that said chip capacitor resonates at a predetermined frequency in cooperation with said strip line.
