Addressing Substrate Coupling in Mixed-Mode IC’s: Simulation and Power Distribution Synthesis
This paper describes new techniques for the simulation and power distribution synthesis of mixed analogldigital integrated circuits considering the parasitic coupling of noise through the common substrate. By spatially discretizing a simplified form of Maxwell’s equations, a three-dimensional linear mesh model of the substrate is developed. For simulation, a macromodel of the fine substrate mes...
متن کاملDynamic Models for Substrate Coupling in Mixed-Mode Systems
In modern monolithic integrated circuits, substrate coupling is a major concern in mixed-mode systems design. Noise injected into the common substrate by fast switching digital blocks may affect the correct functioning or performance of the overall system. Verification of such systems implies the availability of accurate and simulation-efficient substrate coupling models. For frequencies up to ...

چکیده رساله/پایان نامه : تاکنون روشهای متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روشها در شبکه توزیع به دلایلی همچون وجود انشعابهای متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تکفاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...
Measuring mixed-signal substrate coupling
A measurement method is proposed to characterize the substrate coupling between digital and analog sections of a mixed-signal CMOS chip. Induced noise and spurious signals can be measured by a custom-designed analog sensor. This paper proposes a method that, when given such a sensor, allows to measure the crosstalk between digital and analog chip sections. Calibrated sampling scope measurements...
متن کاملEvaluating Noise Coupling Issues in Mixed-Signal 3D ICs
Technology for 3D ICs is slowly becoming mainsteam such that integrating complete mixed digital-analog-RF systems is not only possible but almost unavoidable. Because of the close proximity of the different substrates switching noise from digital circuits are easily coupled through to severely degrade the performance of sensitive analog/RF circuits, as illustrated in Fig 1. In this paper, we ev...
