Title:
温度センサ回路
Document Type and Number:
Japanese Patent JP5189882
Kind Code:
B2
Abstract:
In a temperature sensor circuit, a temperature sensor is configured to output a first voltage corresponding to temperature. A voltage source is configured to output a second voltage having the same nonlinear dependence on the temperature as a nonlinear dependence of the first voltage on the temperature. An amplifier is configured to amplify the second voltage with a first amplification factor to output a third voltage. An inversion amplifier is configured to perform inversion amplification on a difference between the first voltage and the third voltage with a second amplification factor to output a fourth voltage.
