Title:
TEMPERATURE SENSOR AND SENSOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/189429
Kind Code:
A1
Abstract:
A temperature sensor (1) comprises a first resistor bridge circuit (11) having a first resistor (R1) and a second resistor (R2) connected in series between an application terminal of a power supply voltage (Vdd) and an application terminal of a ground potential, and a third resistor (R3) and a fourth resistor (R4) connected in series between the application terminal of the power supply voltage and the application terminal of the ground potential, wherein the first resistor is provided on the ground potential side and has a positive temperature characteristic with respect to a resistance value, the second resistor is provided on the power supply voltage side and has a negative temperature characteristic with respect to a resistance value, the third resistor is provided on the power supply voltage side and has a positive temperature characteristic with respect to a resistance value, and the fourth resistor is provided on the ground potential side and has a negative temperature characteristic with respect to a resistance value.
