Abstract
In this paper, we show how latch-up guard rings, surrounding electrostatic discharge (ESD) protection devices, can reduce the overall performance of the ESD protection network. This issue is addressed by TCAD simulation and experimental results. Design guidelines to cope with this problem are proposed.
