项目摘要
This proposal deals with new design techniques and chipsets for the coming generations of wireless systems, which provide a wider domain of services and work with different standards. The emphasis will be on the design of low power RF, analog and mixed-signal transceiver front-ends in standard MOS technology. Interdisciplinary research work is proposed at the architecture, block, circuit, and device levels leading to CMOS chipsets and single chip front-end design for both cellular and indoor wireless applications. Transceiver architectures for the implementation of multi-standard TDMA and CDMA wireless systems are proposed. Research is then proposed in three main thrusts encompassing RF, baseband and frequency synthesis CMOS design techniques. In the RF part, MOS modeling of GHz Nonlinearities will be studied and optimization techniques using device widths and bias currents as design parameters to achieve low power and high linearity will be developed. The proposed modeling and optimization techniques will then be used in the design of low noise amplifiers, linear power-efficient power amplifiers and mixers with controllable gain settings.In the baseband part, a multi-standard Sigma-Delta data converter architecture is proposed for TDMA (GSM family and DECT) systems while a pipeline architecture is proposed for CDMA systems. Digitally programmable variable gain amplifiers and filters are proposed as part of a CMOS cell library for baseband signal processing. In the frequency synthesis part, techniques for multi-standard frequency synthesizers together with tuning schemes for multi-standard voltage controlled oscillators are proposed.Based on the proposed ideas, several chipsets at the sub-system level will be demonstrated togther with two multi-standard single chip CMOS receivers at the system level, one for TDMA systems and one for CDMA systems (WCDMA, CDMA 2000).A management plan for the proposed activities is provided and a discussion on the education component of this work is included. The proposed work should contribute to the preparation of the nation's critical mass of well trained engineers and scientists that is desperately needed in integrated circuits and systems for future wireless systems. This will enable us to compete effectively on the global scale.
该提案涉及下一代无线系统的新设计技术和芯片组,这些系统提供更广泛的服务领域,并使用不同的标准。重点将放在采用标准MOS技术的低功耗射频、模拟和混合信号收发器前端的设计上。建议在架构、模块、电路和器件级别进行跨学科的研究工作,从而为蜂窝和室内无线应用程序提供CMOS芯片组和单芯片前端设计。提出了实现多制式时分多址和码分多址无线系统的收发信机结构。然后提出了围绕射频、基带和频率合成的三个主要方面的研究。在射频部分,将研究GHz非线性的MOS建模,并开发以器件宽度和偏置电流为设计参数以实现低功耗和高线性度的优化技术。在基带部分,提出了一种适用于TDMA(GSM系列和DECT)系统的多标准Sigma-Delta数据转换器结构,并提出了一种适用于CDMA系统的流水线结构。提出了数字可编程可变增益放大器和滤波器,作为用于基带信号处理的CMOS单元库的一部分。在频率合成部分,提出了多标准频率合成器的技术和多标准压控振荡器的调谐方案。基于所提出的思想,将在分系统级演示几个芯片组,以及系统级的两个多标准单芯片CMOS接收器,一个用于TDMA系统,一个用于码分多址系统(WCDMA,CDMA2000)。为所提议的活动提供了管理计划,并讨论了这项工作的教育部分。这项拟议的工作应该有助于培养美国训练有素的工程师和科学家,这是未来无线系统的集成电路和系统迫切需要的。这将使我们能够有效地在全球范围内竞争。
