摘要： An oscillation circuit includes a control circuit for controlling the source potential of a MOSFET constituting a signal inverting amplifier by using a substrate bias effect. This control circuit controls the threshold voltage of the MOSFET at a low level at the time of making a power source of the oscillation circuit, and controls the threshold voltage of the MOSFET at a high level after stabilization of oscillating operation at the oscillation circuit. Thus, stabilization of oscillating operation and lower power consumption of the oscillation circuit are enabled.
