  • Integrated circuit with a phase-locked loop
    Patent number: 4667168
    Abstract: 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.
