Abstract
An electrostatic discharge protection device is formed using only electrically connected transistors. The transistors include: a first MOS-type transistor forming a clamping circuit coupled between first and second supply nodes; a second MOS-type transistor coupled between the first supply node and a gate terminal of the first MOS-type transistor; and a third MOS-type transistor having a first gate terminal coupled to a gate terminal of the second MOS-type transistor, a second gate terminal coupled to one of the first and second supply nodes, and first and second conduction terminals coupled to the second supply node.
