DISTRIBUTED ELECTROSTATIC DISCHARGE SCHEME TO IMPROVE ANALOG FRONT-END BANDWIDTH OF RECEIVER IN HIGH-SPEED SIGNALING SYSTEM

摘要

Methods and systems are described for selectively providing a signal path from a respective wire of a multi-wire bus to at least one corresponding data signal output node of at least one set of differential data signal output nodes using a respective switching element in a respective set of signal path circuits connected in parallel, and generating a set of discharge currents, each discharge current of the set of discharge currents generated through a respective resistive element in the respective set of signal path circuits to discharge a portion of a voltage pulse on the respective wire of the multi-wire bus to one or more metallic planes via a respective localized ESD protection circuit, the respective resistive element and the respective localized ESD protection circuit connected between the respective wire and the respective switching element.
