| description | PROBLEM TO BE SOLVED: To provide a voltage controlled oscillator(VCO) with which the influence of environment fluctuation upon an output frequency is decreased. SOLUTION: A VCO 5 is provided with plural variable delay cells 10 connected in the form of loop and plural bang-bang modulation circuits 16 connected to digital inputs 110 of respective variable delay cells so as to output digital modulated signals for modulating the operating frequency of VCO. Since a current modulated by the bang-bang modulation circuit is determined only by the ratio of resistance in the circuit because of its design, the stable frequency output can be provided by using the resistor of high accuracy and high reproducibility. |
