A digital temperature sensor is an integrated system that can sense and convert heat measurement from an analog domain to its digital equivalent. However, digital temperature sensing suffers inaccuracy as a result of shift in supply voltage. In this paper, a digital temperature sensor with an improved noise resistant technique for the reliability of digital systems is presented. The proposed method uses a dual delay-line instead of the typical approach that employs conversion and calibration technique to mitigate the effect of noise. The digital temperature sensor is realized using Very High-Speed Integrated Circuit Hardware Description Language and synthesized in Quartus II. The result is a resource efficient digital temperature sensor with a measurement error of -- 1.297°C to 1.799°C over a temperature range of 40°C to 120°C. A temperature sensor resistant to static supply shift of 1.8 to 1.5 supply voltage range, suitable for quick deployment within a Field Programmable Gate Array is achieved. |
