Abstract
Disclosed herein is an oscillation circuit including: a control transistor changing an electric potential at an output terminal thereof by proceeding to one of a conduction state and a non-conduction state in accordance with an electric potential at an input terminal thereof; a transistor as an object of a measurement having a polarity of a channel identical to that of the control transistor, and connected in series with the control transistor between a power source and a ground; a capacitor delaying the change in the electric potential at the output terminal in accordance with a value of a leakage current leaked from the transistor as an object of a measurement when the control transistor proceeds from the conduction state to the non-conduction state; and an inversion circuit inverting the electric potential at the output terminal, thereby feeding the inverted electric potential back to the input terminal.
