摘要
基于TSMC的65nm CMOS工艺,利用CMOS工艺下寄生PNP晶体管的温度特性,设计了一款片内的集成温度传感器。文中分析了CMOS温度传感器的工作原理,重点介绍了感温电路、采样比较电路、逐次逼近型数模转换关键电路的设计实现。试验结果表明,在-40°C~120°C的温度范围内,该温度传感器系统的温度误差小于2°C,功耗为0.75m W。
Based on the 65rim CMOS process of TSMC, by the temperature characteristic of parasitical PNP transistor, on chip integrated temperature sensor is presented. The working principle of integrated temperature sensor is analyzed. And then, intro- duces the implementation of significant, including temperature detection circuit, sampling and comparing circuit, SAR ADC cir- cuit. Testing result shows that the max error under temperature of-40℃- 120 ℃ can below 2℃, and the average power con- sumption was 0.75mW.
