This article briefly describes the concept of the synergy of filtering and shielding and why knowing it is important.

This is the eighth article in a series of articles devoted to the design, test, and EMC emissions evaluation of 1- and 2-layer PCBs that contain AC/DC and/or DC/DC converters and employ different ground techniques [1-7].

Overall, latch-up prevention is one of the most important tasks for both foundries and IC designers. Based on the chip design scheme, designers should select proper solutions to eliminate the ILU and ELU risks in chip design, referencing the foundry guidelines and latch-up silicon data to ensure minimal latch-up risks for the product.
