Substrate noise coupling - the coupling of signals from one node to another via a substrate - is a frequent problem that occurs in integrated circuits. It is critical that today's engineers address this issue and this book shows them how. The book offers detailed guidance on the impact of substrate noise on a wide range of circuits operating from baseband frequencies up to mm-wave frequencies. This unique reference presents case studies to illustrate that careful modeling of the assembly characteristics and layout details is required to bring simulations and measurements into agreement. Practitioners learn how to use a proper combination of isolation structures and circuit techniques to make analog/RF circuits more immune to substrate noise.
