    摘要: An oscillator circuit having a closed loop connection, including: an oscillator for generating an output signal oscillating at a frequency corresponding to a control signal; a frequency/voltage converter for generating a detection signal having a voltage corresponding to a frequency of the output signal; a difference detector for generating a difference signal indicating a difference between the detection signal and a reference signal; and an integrator for generating the control signal by integrating the difference signal.
