物联网设备等嵌入式系统受益于低功耗传感器。我们提出了一个完全集成的比例频率温度传感系统。该温度传感器采用频率依赖型数字输出，取代了高功耗ADC和片内时间基准。系统功耗为195 nW，采用0.5 V电源。采用130 nm技术，在0°至50°范围内，在0.008 mm 2的总面积内实现了0.2 $C^{circ}$的最大温度精度。温度电压电路的实验测量证明，布局后和蒙特卡罗模拟验证，整个系统的设计满足性能要求，是适合于阵列应用。
Embedded systems, such as IoT devices, benefit from low power sensors. We propose a fully-integrated proportional to frequency temperature sensing system. The temperature sensor replaces power hungry ADCs and on-chip time references with a frequency dependent digital output. The system consumes 195 nW, with 0.5 V power supply. The maximum temperature accuracy of 0.2 $C^{circ}$ is achieved across 0° to 50° in a total area of 0.008mm2 in 130 nm technology. Experimental measurements of the temperature to voltage circuit is demonstrated, and post layout and Monte Carlo simulations verify that the total system design meets performance requirements and is suitable for arrayed applications.
