Abstract
An electrostatic discharge (ESD) protection circuit for providing ESD protection to an ESD protected circuit. The protection circuit comprises a signal pad and a crossover network for separating wanted electrical data signals and ESD signals according to their frequency. The protection circuit further comprises a first branch configured to transmit at least a spectral part of the wanted electrical data signals between the signal pad and the ESD protected circuit and a second branch configured to receive the ESD signals from the signal pad. Additionally there is provided a corresponding method, a corresponding integrated circuit chip and a corresponding design structure.
