摘要： An oscillation circuit comprising a control circuit that utilizes the body effect of a substrate bias to control the source potential of a MOSFET that configures a signal inversion amplifier. This control circuit controls the threshold voltage of this MOSFET to be low when power is first applied to the oscillation circuit, and controls the threshold voltage of the MOSFET to be high after the oscillation of the oscillation circuit has stabilized. This makes it possible to ensure that the oscillation circuit oscillates stably and at a low power consumption.
