As the scaling of CMOS nears its end it becomes imperative to a device paradigm that can carry forward device integration to ever-higher densities. The most daunting challenge facing the industry in the scaling of CMOS is power density. This is seen in the rapid increase in the total power dissipated by ICs, and even more ominously in the power per unit area. An attractive route to continue progress in devices is to develop a paradigm where the energy required is orders of magnitude lower than that possible in CMOS. A nanoelectronics paradigm called quantum-dot cellular automata (QCA) holds this promise, where by using quasi-adiabatic clocking the switching energy can be below kT. In addition clocked QCA cells can provide true power gain for logic level restoration. While nanoelectronics is perhaps the key technology for the future of electronics, it should be recognized that CMOS will have a place in systems long after the end of scaling, and implementations of nanoelectronics will necessarily need to interface with CMOS. CMOS has a tremendous number of advantages which can exploited, and the extensive CMOS infrastructure should be leveraged to make the smoothest possible transition to the nanoelectronic paradigm. For example, clocking and interfacing to the outside world would be handled by CMOS circuitry, while computation tasks would be handled by the low-power nanoelectronic circuitry. Combinations of nanoelectronics and CMOS will be an excellent way to implement electronic systems. The proposed project will explore the issues of interfacing nanoelectronics and CMOS.

随着CMOS的缩放接近其末端，必须将可以将设备集成到更高密度的设备范式中。在CMO的扩展方面，该行业面临的最艰巨的挑战是功率密度。这在ICS消散的总功率的迅速增加中，甚至更不祥的是每单位区域的功率。在设备中继续进展的一个有吸引力的途径是开发一个范式，在该范式中所需的能量比CMO中的数量级低。一种称为量子点蜂窝自动机（QCA）的纳米电子范式持有这一承诺，其中使用准绝热时钟的开关能量可以低于Kt。另外，时钟QCA单元可以为逻辑水平恢复提供真正的功率增益。尽管纳米电子学也许是电子产品未来的关键技术，但应该认识到，CMO在扩展结束后很长一段时间在系统中占有一席之地，并且纳米电子学的实现必然需要与CMO进行互动。 CMO具有可利用的大量优势，并且应利用广泛的CMOS基础架构，以使其最平稳的过渡到纳米电子范式。例如，CMOS电路将处理与外界的时钟和接口，而计算任务将由低功率纳米电流电路处理。纳米电子和CMO的组合将是实施电子系统的绝佳方法。拟议的项目将探讨接口纳米电子和CMO的问题。
