MEASUREMENT CIRCUIT, MEASUREMENT METHOD IMPLEMENTED BY SAME, AND TEMPERATURE SENSOR

WIPO Patent Application WO/2023/155062

A1

Provided is a measurement circuit which can be applied to a temperature sensor and is in direct proportion to absolute temperature. The measurement circuit is provided with a first measurement output terminal (23) and a second measurement output terminal (24). The measurement circuit comprises: a plurality of measurement elements (35) for measuring an object to be measured to obtain measurement results, and a switch assembly (34), wherein each measurement element (35) is connected to the first measurement output terminal (23) or the second measurement output terminal (24) by means of the switch assembly (34), and the first measurement output terminal (23) and the second measurement output terminal (24) are used for outputting the measurement results; and the switch assembly (34) is configured to: within any time period, connect at least one measurement element (35) to the first measurement output terminal (23), and connect the remaining measurement elements (35) to the second measurement output terminal (24). By performing dynamic compensation on the detection results of the detection elements (35), a mismatch problem caused by fixedly connecting various detection elements (35) to one output terminal is avoided, and detection errors are reduced.
