CONACYT: Design and Implementation of a Wireless Communication System using BiCMOS Technologies

9613722 Sanchez-Sinencio本提案的主要目标是使用统一的方法识别、表征、建模和设计在无线系统应用中必不可少的算法和设备。这涉及到从系统角度到晶体管级实现的(自上而下)分层设计。将确定系统架构、BiCMOS电路实现、成本、功耗和不同级别的性能之间的权衡。这项研究将产生重要的实用成果，形成许多无线通信产品的基础，特别是那些将用于即将到来的个人通信系统(PCS)和工业、科学和医疗(ISM)频段通信的产品。在构建集成电路形式的完整无线通信产品与混合(带有芯片外组件)产品方面的权衡将是拟议研究的关键组成部分。该方案中提出的工作包括理论、软件仿真和硬件实现。这种方法的独特性是基于两个小组的协调努力，他们在通信和微电子电路方面取得了公认的成就。来自提出这个项目的两个机构的教职员工和研究生之间预计会有大量的互动。得克萨斯农工大学将在通信系统架构、多址技术(如码分多址、时分多址等)、信号处理算法、混频器以及有源和无源滤波器方面做出贡献。INAOE的贡献将主要集中在关键构建块的BiCMOS电路设计上。这些模块包括前端低噪声放大器(LNA)、功率放大器、信道编解码器和相关器。所提出的设计方案的可行性和性能将首先通过软件仿真来验证，包括权衡、重要模块的硅片原型的实验验证以及一些系统应用结果。这项提案研究的成功结束将导致设计无线通信系统的实用、统一的设计方法，特别是那些用于在ISM频段运行的PCS和未经许可的设备的系统。预计将在系统、构建块和硬件级别做出贡献，并确定它们之间的相互关系。这项研究将对我们大学的无线研究和教育基础设施产生重要影响，因为已经有相当数量的学生参与其中。为这些学生提供的资金不仅可能来自这项提案中要求的支持，还将在未来三年来自德克萨斯农工大学工程学院和电气工程系以及德克萨斯仪器公司目前提供的超过50万美元的支持。这项拟议研究的实用性和相关性是建立在强大的行业联系和学术界与大学之间强大的思想交流基础上的。***

9613722 Sanchez-Sinencio The main goal of this proposal is to identify, characterize, model, and design algorithms and devices that are essential in wireless system applications, using a unified approach. This involves a (top-down) hierarchical design all the way from the system point of view, to the transistor level implementation. Tradeoffs between system architecture, BiCMOS circuit implementations, cost, power consumption, and performance at different levels will be identified. This research will yield important practical results that form the basis for many wireless communication products, and specifically those to be used for the upcoming personal communication systems (PCS) and in communication over the industrial, scientific and medical (ISM) bands. The tradeoffs in building complete wireless communication products in integrated circuit form, versus hybrids (with off-chip components) will be a key component of the proposed research. This work proposed in this proposal encompasses theory, software simulation, and hardware implementations. The uniqueness of the approach is based on the coordinated effort of two groups with proven accomplishments in communications and microelectronics circuits. Heavy interaction between both faculty members and graduate students from the two institutions proposing this project is expected. The Texas A&M University contribution will be in the communication system architectures, multiple-access techniques (i.e. CDMA, TDMA, etc.), signal processing algorithms, mixers, and active and passive filters. The INAOE contribution will be mainly in the BiCMOS circuit design of key building blocks. These blocks include the front-end low noise amplifier (LNA), power amplifiers, channel encoders/decoders, and correlators. The feasibility and performance of the proposed designs will be verified first by software simulation involving tradeoffs, experimental verification b silicon chip-prototypes of important building blocks, and some system applications resul ts. A successful conclusion of this proposal research will lead to practical, unified design methodologies for designing wireless communication systems, especially those for PCS and unlicensed devices operating in the ISM bands. Contributions at the system, building block, and hardware levels and their interrelations are anticipated. This research will have an important effect on the infrastructure of wireless research and education in our universities, since a significant number of students are already involved. Funding for these students will come not only potentially from the support requested in this proposal, but also from present support, exceeding half a million dollars, from the College of Engineering and the Department of Electrical Engineering at Texas A&M University, as well as from Texas Instruments, over the next three years. The utility and relevance of the proposed research is based on substantial industrial ties, and strong exchange of ideas between academia and university. ***
