Abstract: |
The invention relates to a temperature sensor of a digital CMOS sheet in the field of temperature monitoring domain. It uses the linear relationship between the transistor critical voltage and the temperature to separately design two project temperature sensing circuit based on the relaxation oscillator and the Schmitt trigger. The accuracy of the two temperature sensors are below 1 degree. It adopts all CMOS structure at the same time. |
