Abstract
An overtone crystal oscillating circuit is disclosed which includes a complementary MOS inverter formed of P and N channel MOS transistors, a crystal resonator and a feedback resistor which are connected between input and output terminals of the complementary MOS inverter, and first and second capacitors respectively connected to the input and output terminals of the complementary MOS inverter. The crystal oscillating circuit is further provided with a series circuit formed of an inductor and a capacitor and connected in parallel with the first or second capacitor to form a parallel resonant circuit.
