Abstract
A clamp circuit includes an electrostatic discharge (ESD) detection circuit coupled between a first node and a second node. The clamp circuit further includes a first transistor of a first type. The first transistor has a first gate coupled to at least the ESD detection circuit by a third node, a first drain coupled to the first node and a first source coupled to the second node. The clamp circuit further includes a charging circuit coupled between the second node and the third node, and configured to charge the third node during an ESD event at the second node.
