The speed of operation of the oscillator circuit is increased. An integrated circuit for such an oscillator circuit is also provided. The oscillator circuit has an amplifier portion consisting of CMOS inverters connected in cascade. MOS transistors forming the CMOS inverters have channel widths that decrease successively from the first stage to the last stage to improve the amplification factor of the amplifier portion at high frequencies. This makes it possible to amplify weak oscillation output from the quartz oscillator (XL). A filter circuit produces a peak of negative resistance at a frequency higher than conventional. This permit oscillation operation at higher frequencies.
