    Abstract: The present disclosure relates to the field of biometric parameter measurement, and in particular, to a temperature measurement circuit, a temperature measurement method, a temperature and light intensity measurement circuit, a temperature and light intensity measurement method, a chip, a module, and an electronic device. A temperature signal is obtained based on an output voltage of a differential amplifier circuit when a non-inverting input terminal of the differential amplifier circuit is unload, an output voltage of the differential amplifier circuit when the non-inverting input terminal of the differential amplifier circuit is connected to a calibration resistor, and the output voltage of the differential amplifier circuit when the non-inverting input terminal of the differential amplifier circuit is connected to a thermistor, which improves the accuracy of the temperature measurement.
