可校准电源偏差并基于标准单元的温度传感器

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

提出了基于双电压点校准的温度传感器。所提出的传感器配合双电压点校准方法可以大幅度降低供电电压变化引起的温度测量误差,且完全基于标准单元设计,无需版图定制,易于使用标准的数字电路设计流程实现。实验表明,相比之前提出的无双电压点校准的双环温度传感器,0.1 V电源电压偏差引起的误差可从90℃降低到28.5℃。

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 dual-ring sensor.
