Abstract

Provided is a compensation circuit capable of improving compensation precision for manufacturing variations. The compensation circuit includes a manufacturing variation detection circuit which detects manufacturing variation of a transistor based on a first voltage output from an output terminal of the transistor having an input terminal applied with a substantially constant first current to temperature or based on a second current output from an output terminal of the transistor having an input terminal applied with a substantially constant second voltage to temperature, and a voltage generation circuit which generates a supply voltage supplied to an electric circuit based on the manufacturing variation. The first current corresponds to the substantially constant second voltage to temperature, and the first voltage corresponds to the substantially constant second current to temperature.
