Patent ID: 7003273

Claim:
A temperature compensating circuit for compensating an operation of an electronic circuit having a temperature characteristic in accordance with an ambient temperature of the electronic circuit, comprising: temperature detecting means for detecting an ambient temperature of the electronic circuit; and temperature compensating control means comprising: first storage means for storing corrected temperatures each of which corresponds to one of a plurality of detected ambient temperatures, the detected ambient temperatures being within a temperature range that is to be corrected and that is a detection characteristic of the temperature detecting means, and said corrected temperatures being set at values for correcting detection errors in the detected ambient temperatures; second storage means for storing operation correction data prepared for correcting a temperature characteristic of the electronic circuit; and correction processing means for selectively reading, from the first storage means, one of the corrected temperatures corresponding to the ambient temperature detected by the temperature detecting means, and for correcting the operation of the electronic circuit on the basis of the corrected temperature and operation correction data stored in the second storing means corresponding to the corrected temperature.
