ABSTRACT:
The present invention relates to a resonance type voltage control oscillator. The voltage control oscillator includes an inductor unit including two inductances serially coupled to each other, a variable capacitance unit coupled to the inductor unit in parallel, a negative resistance unit coupled to the inductor unit in parallel, a first variable resistor having a resistance value corresponding to an input first control signal, a second variable resistor having a resistance value corresponding to an input second control signal, and a variable resistor control circuit unit generating the first and second control signals and controlling respective resistance values of the first and second variable resistors. The variable resistor control circuit unit controls the respective resistance values of the first and second variable resistors to set current flowing in the inductor unit, the variable capacitance unit and the negative resistance unit to a desired current value.
