Abstract
An electrostatic discharge protection circuit includes an input node coupled to receive an input signal and an output node coupled to output the input signal to an internal circuit. A first inductor is coupled to the input node and to the output node, and a second inductor is coupled to the output node and to a first power supply node through a resistance. A plurality of protection devices are coupled to the first and second inductors and are disposed in parallel with each other.
