ABSTRACT:
A voltage controlled oscillator circuit comprises a variable current generator to supply an operation current to a voltage controlled oscillator, the voltage controlled oscillator to include a resonance circuit having a variable capacitor and inductor, and to output an output signal having an amplitude based on a current generated by the variable current generator, and a first optimization circuit to which the output signal is inputted, the first optimization circuit generating and outputting a current setting signal based on an amplitude change of the output signal corresponding to a change of a current outputted by the variable current generator to the variable current generator.
