Abstract
An electrostatic discharge protection unit includes a channel, a passive filter, and an electrostatic discharge protection circuit. The passive filter and the electrostatic discharge protection circuit are formed on a substrate. The electrostatic discharge protection circuit couples the channel to the passive filter. A method includes, for a channel having a bandwidth determining the bandwidth, and generating a transfer function for a passive filter which when combined in series an electrostatic discharge protection circuit and the channel yields a combination transfer function which has a combination bandwidth that is greater than the channel transfer function bandwidth.
