Abstract
In a crystal-controlled oscillator circuit comprising a complementary-MOS inverter provided with a crystal in the feed-back circuit, an initiation circuit is provided which comprises another complementary-MOS inverter connected in parallel to said MOS inverter only at the time of initiation. This oscillator circuit includes a parallel circuit connection of two complementary MOS inverters at the time of initiation and hence has a large driving power and a short oscillation initiation time. Because of rendering one complementary MOS inverter to be cut off at the time of normal oscillation, the power consumption is reduced.
