Abstract

Methods and apparatuses to terminate transmission lines using voltage limiters. In one aspect, a termination circuit is integrated on a substrate to terminate a transmission line connected from outside the substrate. The termination circuit includes: a port to interface with the transmission line; a first resistive path including a first voltage limiter coupled between the port and a first power supply voltage provided on the substrate resistive path; and a second resistive path including a second voltage limiter coupled between the port and a second power supply voltage provided on the substrate.
