摘要
A ring oscillator includes an odd number of unit circuits connected in series each of which includes an inverter. Each of the unit circuits includes the inverter and a MOSFET. The MOSFET is an FET which is a temperature sensor, and uses a drain-source leakage current in a state that the FET is normally turned off.
