Abstract
A structure is designed with an external terminal (100) and a reference terminal (102). A first transistor (106) is formed on a substrate. The first transistor has a current path coupled between the external terminal and the reference terminal. A second transistor (118) has a current path coupled between the external terminal and the substrate. A third transistor (120) has a current path coupled between the substrate and the reference terminal.
