Substrate Noise Coupling in Analog/RF Circuits
Stephane Bronckers, Geert Van der Plas, Gerd Vandersteen and Yves Rolain
Substrate noise coupling—the coupling of signals from one node to another via a substrate—is a frequent problem that occurs in integrated circuits especially where digital circuits or several analog device types are integrated on the same die. It is critical that today's engineers address this issue, as analog circuits are widely used to interface with the outside world and wireless applications are used pervasively. Substrate Noise Coupling in Analog/RF Circuits offers detailed guidance on the impact of substrate noise on a wide range of circuits operating from baseband frequencies up to millimeter-wave frequencies.
This book investigates in detail the mechanisms of creation and propagation of substrate noise and analyzes its impact on analog circuits. Emphasis is on the modeling and simulation of the effects, as needed by circuit designers during their designs, as well as on design measures to alleviate the problems. It presents case studies to illustrate that careful modeling of the assembly characteristics and layout details are required to bring simulations and measurements into agreement.
Practitioners will learn how to use a proper combination of isolation structures and circuit techniques to make analog/RF circuits more immune to substrate noise. They will learn how to simulate noise sources and how to analyze the effectiveness of the design measures that they should take. In this way, they will be able to design better and more robust mixed-signal systems. Substrate Noise Coupling in Analog/RF Circuits is a practical and well organized book that should be useful to practicing engineers and designers.
