摘要

A crystal oscillation circuit that oscillates stably with a low power consumption includes an inverting amplifier, a crystal oscillator, and a feedback circuit that inverts the phase of an output from this inverting amplifier and feeds it back as an input. The inverting amplifying includes first and second semiconductor switching elements. The sum of the absolute value of the threshold voltage of the first semiconductor switching element and the absolute value of the threshold voltage of the second semiconductor switching element is set to be greater than or equal to the absolute value of the potential difference between first and second potentials, in order to prevent the first and second semiconductor switching elements from being on simultaneously.
