碩士<br>國立交通大學<br>電信工程研究所<br>99<br>A low power and high precision temperature sensing unit is an essential unit in environmental and biomedical temperature sensing application. With the development of Integrated-Circuit(IC) technology, the traditional temperature sensor is not suitable for integrating into low power VLSI circuit. Therefore, how to implement a low voltage, low power temperature sensor which can be easily integrated with advanced SOC is an important research. In this thesis, we implemented a 1.8V 53.4uW CMOS temperature sensor with -55°C to 125°C temperature range and 0.25°C resol

Abstract:

碩士<br>國立清華大學<br>電機工程學系<br>95<br>Due to the advance in CMOS technology and design complexity, more power is dissipated in smaller die area, thus the thermal density of modern VLSI systems is becoming a critical issue. High die temperature can not only degrade circuit performance but also leads to thermal runaway. Therefore, continuous monitoring of die temperature is crucial. In this thesis, a CMOS smart temperature sensor without conventional ADC or bandgap reference is proposed for thermal management of VLSI system. The accuracy is within ±0.8 °C over the temperature range of 0 °C to 125 °C a

This study used NOT gates in series to realize a temperature-sensing delay line (TDDL) to perform the temperature-to-time conversion first. Then, an all-digital pulse-shrinking unit (ADPSU) was proposed to convert the time into the corresponding digital output. This enabled the proposed sensor can be implemented using all-digital design.

Abstract:

Temperature sensors are widely used in microprocessors to monitor on-chip temperature gradients and hot-spots, which are known to negatively impact reliability. Such sensors should be small to facilitate floor planning, fast to track millisecond thermal transients, and easy to trim to reduce the associated costs. Recently, it has been shown that thermal diffusivity (TD) sensors can meet these requirements. These sensors operate by digitalizing the temperature-dependent delay associated with the diffusion of heat pulses through an electro-thermal filter (ETF), which, in standard CMOS, can be re

Nowadays, the studies of medicines usually have been done by laboratory scale instruments, the results of experiments are correct, but this process wastes too much time and resources, nay, the results are not able to be observed immediately. As a result, we hope that this research will provide a bio-chip with high sensitivity and real-time detection, and it could record infection process of WSSV immediately.

Abstract:

Integrated temperature sensors play an important role in enhancing the performance of on-chip power and thermal management systems in today's highly-integrated system-on-chip (SoC) platforms, such as microprocessors. Accurate on-chip temperature measurement is essential to maximize the performance and reliability of these SoCs. However, due to non-uniform power consumption by different functional blocks, microprocessors have fairly large thermal gradient (and variation) across their chips. In the case of multi-core microprocessors for example, there are task-specific thermal gradients across d
