VOLTAGE-CONTROLLED OSCILLATOR AND INTEGRATED CIRCUIT DEVICE PROVIDED WITH SAME

摘要

PROBLEM TO BE SOLVED: To provide a voltage-controlled oscillator with an output maintained at a constant level at all times independently of the oscillated frequency.

SOLUTION: The voltage-controlled oscillator 1a includes: a voltage-controlled oscillation circuit VCO for oscillating the frequency in response to a control voltage; and a limiter circuit LMT placing a limit of a prescribed level to an output of the voltage-controlled oscillation circuit VCO.
