    摘要： Implementations are presented herein that include an electrostatic discharge (ESD) protection circuit. The ESD protection circuit includes a first transistor and a second transistor. The first transistor has a first terminal that is coupled to a first supply line and a bulk that is coupled to a second supply line. The second transistor has a first terminal that is coupled to the second supply line, a bulk that is coupled to the first supply line and a second terminal that is coupled to a second terminal of the first transistor to define a protected node. The ESD protection circuit further includes a current limiting element that has a first terminal that is coupled to the protected node.
