1. a kind of method of adjustment of inductance capacitance parallel resonance chamber resonant frequency, it is characterised in that including voltage-controlled to inductance capacitanceThe resonant frequency of first inductance capacitance parallel resonance chamber of oscillator is calibrated;

  • Obtain frequency control parameters of the first inductance capacitance parallel resonance chamber under current resonant frequency;

    According to the frequency control parameters by the resonant frequency of the second inductance capacitance parallel resonance chamber of circuit module adjust toThe gap of its frequency input signal is within preset value, the second inductance capacitance parallel resonance chamber and first inductance capacitanceParallel resonance chamber has identical control rule;

    It is described that there is identical control rule to include:

    The second inductance capacitance parallel resonanceThe switched capacitor array of the switched capacitor array of chamber and the first inductance capacitance parallel resonance chamber has identical frequency tuningThe digit of scope, coded system and control bit;

    Or the switched capacitor array of the second inductance capacitance parallel resonance chamber be byThe switched capacitor array of the first inductance capacitance parallel resonance chamber is zoomed in and out according to preset ratio and obtained.
