本研究的目的是开发一个集成的解决方案，低成本的约翰逊噪声温度计（JNT）的速度明显快于目前可用的，并证明其实际应用于片上温度测量。该方法遵循与启用其他主要JNT相同的奈奎斯特噪声原理，但重点关注最广泛使用的工业温度范围，在该范围内灵敏度和带宽要求大幅放宽，并结合数项创新的电路设计和数字信号处理技术，将测量时间从数小时缩短到毫秒，以供实际使用。这项研究的主要学术价值在于开发了JNT的第一个实用集成解决方案。另一个智力上的优点是为嵌入式应用提供准确且固有线性的温度传感器和/或传感器基准。其他智力优点包括新的电路设计技术，消除速度瓶颈的主要JNT，采样和后处理技术，显着减少测量误差。最后，本研究为其他嵌入式温度传感器引入了一种新的片上多温度自校准方案，该研究的直接广泛影响是集成温度计在科学，工业和日常使用中的广泛适用性。新技术也很有可能被工业界采用，并产生直接的经济影响。计划采取有针对性的办法，促进招收和培训女生和少数民族学生。 一些噪声和温度测量技术和实验室实验将纳入本科课程。最后，非传统传播活动将进一步扩大项目的影响。

The objective of this research is to develop an integrated solution to low-cost Johnson noise thermometers (JNT) with significantly faster speed than currently available, and to demonstrate its practical application to on-chip temperature measurement. The approach is to follow the same Nyquist noise principle that enabled other primary JNTs, but to focus on the most widely used industrial temperature range over which sensitivity and bandwidth requirements are drastically relaxed, and to reduce measurement time from hours to milliseconds for practical use by integrating several innovative circuit design and digital signal processing techniques.The primary intellectual merit of the research is in developing the first practical integrated solution to JNTs. A further intellectual merit is in providing an accurate and inherently linear temperature sensor and/or sensor reference for embedded applications. Other intellectual merits include novel circuit design techniques for eliminating speed bottlenecks in primary JNTs, and sampling and post-processing techniques for significantly reducing measurement errors. Finally, this research introduces a new on-chip multi-temperature self-calibration scheme for other embedded temperature sensors.An immediate broader impact of the research is the wide applicability of the integrated thermometer in science, industry and everyday uses. The new technology also has a high probability of being adopted by industry and creating a direct economic impact. Targeted approaches are planned to facilitate recruiting and training of female and minority students. Several noise and temperature measurement techniques and laboratory experiments will be incorporated into undergraduate courses. Finally, nontraditional dissemination activities will further broaden the project's impact.
