<p><P>PROBLEM TO BE SOLVED: To provide a temperature detection circuit wherein an output voltage of the temperature detection circuit is ratiometric operation in proportion to a supply voltage, and a differential signal output does not generate an error in a detection temperature even when a common mode potential is fluctuated, and the output voltage of the temperature detection circuit is changed linearly to the temperature. <P>SOLUTION: This temperature detection circuit is constituted by using a resistor wherein the reciprocal of a resistance value is changed linearly to the temperature, a resistor wherein the resistance value is changed linearly to the temperature, and an entire differential error amplifier. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
