Standard-Cell-Based Temperature Sensor with Calibrated Supply Noise Tolerance

A standard cell based temperature sensor with calibrated tolerance for supply shift is proposed.Traditional digital circuit temperature sensors have large error caused by supply voltage shift since they are sensitive to supply voltage.The pure standard cell attribute makes the sensor very easy to be designed with normal digital circuit design flow.After 2-voltage calibration,error caused by almost 0.1 V supply shift is reduced to 28.5℃ compared to 90℃ of previously proposed dualring sensor.
