Clock signal generating device with complementary MOS transistors
 Disclosed is a clock signal generating integrated circuit device comprising a quartz crystal oscillator section and a multistage frequency divider section. The crystal oscillator section and each frequency divider stage includes respectively complementary insulated gate field effect transistors. According to the present invention, the high frequency-operated field effect transistors have a lower threshold voltage than the remaining field effect transistors, so that the occupied area of the oscillator section can be decreased and simultaneously the power dissipation can also be reduced.
