McNeill, John A. Worcester理工学院CISE研究仪器：用于特定应用架构的原型设备这项研究仪器补助金使两个不同的研究项目成为可能：-集成622Mhz电信合成器-方法扩展：本提案中的设备被要求支持一类低噪声集成振荡器设计方法的研究。在无线通信、高速微处理器、磁盘驱动器读取通道和过采样数据转换等应用中，需要稳定的低噪声振荡器作为时间和频率参考。振荡器设计方法的关键见解是系统级性能与电路级考虑（如热噪声）所施加的基本限制的联系。该方法正在向更高的速度（工作频率为2.5GHz）、更低的功耗和更多的制造技术（CMOS和BiCMOS）领域扩展。设计方法的测试是通过设计、制造和测试实现系统级功能的集成电路进行的。所要求的测试设备能够在时域和频域进行精确的系统和电路级测量，对于验证该方法的理论预测至关重要。所要求的设备也是一个正在进行的项目的一部分，该项目旨在为本科生和研究生在完整的混合信号集成电路设计过程中建立一个设计和测试环境。这种能力支持的活动包括跨学科的协作工作和本科生参与研究。

9617333 McNeill, John A. Worcester Polytechnic Institution CISE Research Instrumentation: Protyping Equipment for Application Specific Architectures This research instrumentation grant enables two distinct research projects: - Integrated 622Mhz Synthesizer for Telecommunications - Methodology Extensions: Low Noise Integrated Circuit Design for Telecommunication Systems The equipment in this proposal is requested to support research into a design methodology for a class of low noise integrated oscillators. Stable, low noise oscillators are required as time and frequency references in applications such as wireless telecommunications, high speed microprocessors, disk drive read channels, and oversampled data conversion. The key insight of the oscillator design methodology is the linkage of system-level performance to fundamental limits imposed by circuit-level considerations such thermal noise. The methodology is being extended in the areas of higher speed (operating frequencies to 2.5GHz), lower power consumption, and more fabrication technologies (CMOS and BiCMOS). Testing of the design methodology is carried out through design, fabrication, and test of integrated circuits that implement a system-level function. The requested test equipment, which enables precise system- and circuit-level measurement in both the time and frequency domains, is essential to verify the theoretical predictions of the methodology. The requested equipment is also part of an ongoing program to establish a design and test environment for education of undergraduate and graduate students in the complete mixed-signal integrated circuit design process. The activities supported by this capability include interdisciplinary collaborative work and involvement of undergraduate students in research.
