Temperature sensing circuit and electronic device using same

摘要

A temperature sensing circuit that detects a given temperature includes a first differential input circuit and a second differential input circuit connected to the first differential input circuit. The first differential input circuit is configured to provide a first offset voltage with no temperature coefficient. The second differential input circuit is configured to provide a second offset voltage with a non-zero temperature coefficient. The given temperature is detected based on the first offset voltage and the second offset voltage. An electronic device using such a temperature sensing circuit is also disclosed.
