Variations-Sensitive Digital CMOS Circuits

下一代数字微芯片*数字微芯片在从智能手机到汽车、从个人电脑到飞机的广泛应用中的使用呈指数级增长。*微芯片使用量的指数增长之所以成为可能，是因为研究人员，包括滑铁卢大学的Mohamed Elmasry教授和他的团队，在过去37年里每两年能够以一半的成本将芯片的性能和功能翻一番。*微芯片的成本与产量直接相关；制造的硅晶片中优质芯片的数量。收益率取决于几个参数。为了提高它，必须在设计阶段考虑这些参数。*在当今微芯片面积不断扩大的今天，制造参数的广泛变化以及从芯片的一个部分到另一个部分的温度和电源电压的变化，对以高成品率制造微芯片构成了重大挑战。*本研究的目标是探索对制造参数变化以及芯片上温度和电源电压变化不太敏感的新型数字电路。*

Next Generation Digital Microchips ** **The usage of digital microchips in a wide range of applications from smart phones to cars and from PCs to aircrafts has been exponential.** **This exponential increase in microchip usage was only possible because researchers, including the University of Waterloo's Professor Mohamed Elmasry and his team, were able to double chip performance and functionality at half the cost every two years for the past 37 years.** **The cost of a microchip is directly related to yield; the number of good chips within a fabricated silicon wafer. Yield depends on several parameters. To enhance it these parameters must be taken into considerations in the design phase.** **In today's ever increasing area of microchips, wide variations in fabrication parameters and the changes in temperature and supply voltage from one part of the chip to the other pose a major challenge to fabricate microchips at high yield. ****The objective of this research is to explore novel digital circuits that are less sensitive to variations in fabrication parameters and on-chip changes in temperature and supply voltage.******
