Abstract

The latest European EMC regulations push the IC market towards more "quiet" devices with reduced electro-magnetic radiation and ground bouncing. A well-known method to reduce ground bounce of CMOS bus driver outputs is to form the NMOS output transistor gate partially in a serpen- tine shape, see Figure 1 for a typical layout scheme and Figure 2 for an example of electrical schemat- ics.
