摘要： The IC chip consists of electronic circuits wherein voltage control oscillator whose oscillation frequency is dependent on the product of the resistance value of a resistor element and the electrostatic capacity of a capacitor element is provided; said capacitor element consists of the first variable capacitor; said voltage control oscillator comprises said capacitor consisting of said first variable capacitor; said first variable capacitor is controlled by the output obtained by detecting the output signal of said voltage control oscillator by its phase, using the predetermined reference signal, whereby the oscillation frequency of said voltage control oscillator can be made to agree with the frequency of said reference signal. Furthermore, the characteristic of said electronic circuit is dependent on a second resistor element and a second variable capacitor element; said second variable capacitor is controlled by the output obtained by the phase detection so that dispersions of the resistance value of the resistor element and the electrostatic capacity of the capacitor element in said electronic circuit are absorbed automatically.
