Abstract
A temperature detector circuit for converting a forward drop voltage of a diode to digital data by means of an AD converter is provided. In order to restrict an occurrence of an output error caused by dispersion in diode manufacture, correction data according to digital data obtained by the AD converter is stored in advance in a storage circuit under a known arbitrary temperature condition, and subtraction is performed between digital data obtained by the AD converter under an unknown temperature condition and correction data read from a storage circuit, thereby to perform correction.
