Analog integrated circuits (IC's) designers have been forced, primarily by economics, to develop circuits using the dominant digital CMOS technologies. In CMOS the supply voltage continues to scale down below 1 V. Even if the process technology didn't require reduced supply voltages, the rapidly growing reliance on battery-powered microsystems (such as portable consumer electronics, computing devices, wireless communication systems, and biomedical implants) has led to an increase need for high performance ICs that operate under low supply voltage, consume low-power and capable of high frequency operation. On top of this continuous drive for performance improvement, there is also the continuing march of Moor's Law, which drives microsystems to be implemented in nanometer CMOS process. High performance analog circuits become increasingly difficult to implement in nano-scale CMOS due to the reduced intrinsic small signal gain and device headroom, making previously acceptable analog topologies and technologies become obsolete. Therefore, new specialized design techniques, new topologies and new architectures are needed. This provides the motivation for this research project. It explores low-voltage and low-power analog IC's design techniques and develops new high performance analog devices for future microsystems implementation.

模拟综合电路（IC）设计师主要是由经济学强迫使用主要数字CMOS技术来开发电路的。在CMOS中，电源电压继续缩小到1 V以下。即使过程技术不需要降低供应电压，也迅速依赖电池供电的微型系统（例如便携式消费电子设备，计算机设备，无线通信系统和无线电话，以及生物医学植入物）导致对在低供应电压下运行的高性能IC的需求增加，消耗低功率并能够进行高频操作。除了这种不断提高性能的驱动力之外，还有摩尔定律的持续游行，该法律推动了在纳米CMOS过程中实施的微型系统。由于固有的小信号增益和设备净空的减少，高性能模拟电路在纳米级CMO中变得越来越难以实施，因此以前可接受的模拟拓扑结构和技术变得过时了。因此，需要新的专业设计技术，新的拓扑和新的架构。这为该研究项目提供了动力。它探索了低压和低功率模拟IC的设计技术，并为未来的微型系统实现开发了新的高性能模拟设备。
