The ESD design window concept

The ESD design window is a concept used by IC designers to define the requirements for the ESD protection devices. This article provides information on the different aspects like robustness, effectiveness and transparency of ESD devices.

Adapting Diode triggered SCRs (part 2)

In this article, I wish to introduce you to how we can use diode triggered silicon controlled rectifiers (DTSCRs) for on-chip ESD protection. I will explain how its 3 main parameters – trigger voltage, holding voltage and failure current – can be tuned in order to protect ICs with very different characteristics.
