提出一种CMOS智能温度传感器，通过批量校准技术实现了-70°C至130°C范围内±0.25°C(3σ)的高精度，解决了传统单个校准成本高的问题，精度相比现有技术提升2倍。
Delft University of Technology, Delft, Netherlands Federal University of Santa Maria, Santa Maria, Brazil 3 Holst Centre, Eindhoven, Netherlands 2 A major contributor to the total cost of precision CMOS temperature sensors is the cost of trimming and calibration. Significant cost savings can be obtained by batch calibration, but this is usually at the expense of an equally significant loss of accuracy [1]. This paper presents a CMOS temperature sensor with a batchcalibrated inaccuracy of ±0.25°C (3σ) from -70°C to 130°C, which represents a 2× improvement over the state of the art [2]. As in [2], individual trimming reduces the sensor’s inaccuracy to ±0.1°C (3σ) over the military range: -55°C to 125°C. The sensor draws 25µA from a 2.5V to 5.5V supply, which is significantly less than commercial products with comparable accuracy [3,4], and 3× less than the sensor reported in [2]. This improved performance is the result of a systematic optimization of the critical accuracy-power tradeof
