6 concepts to replace dual diode ESD protection

When the conventional dual diode based ESD protection is causing problems ESD designers can use one of these 6 concepts.

Local ESD protection in analog IOs

The most common ESD protection for I/Os consist of two diodes. To cover all the different stress combinations a rail clamp is required. In this article we discuss another option. For many interfaces a local ESD protection clamp is actually a better option.
