ABSTRACT:
An oscillator circuit in a semiconductor substrate of an integrated circuit, includes a gain correction circuit portion connected between the output terminal of the feedback circuit portion and the input end of the amplifier circuit portion composed of MOS transistors. The gain correction circuit portion suppresses the excessive amplitude of the output signal of the feedback circuit portion, so that the characteristic of the waveform of the output signal of the oscillator device is improved.
