Low power dissipation crystal oscillator - has IGFETs in inverter circuit and excitation circuit with crystal resonator and capacitive load

摘要

The low power dissipation crystal oscillator comprises an inverter circuit including a pair of complementary insulated gate field-effect transistors and an excitation circuit. This is connected between the output and the input of the inverter circuit. The excitation circuit comprises a crystal resonator and a pair of capacitive loads, wherein different DC bias potentials are applied to the gates of the field-effect transistors, respectively, in order to cause the power dissipation to be extremely reduced.
