Title: Balanced charge-recycling repeater link

Abstract

A balanced, charge-recycling repeater link is disclosed. The link includes a first set of segments operating in a first voltage domain and a second set of segments operating in a second voltage domain. The link is configured to transmit a first signal over at least one segment in the first set of segments and at least one other segment in the second set of segments. Each segment of the link includes at least one active circuit element configured to charge or discharge one or more corresponding interconnects within the link and a level shifter configured to shift the level of a signal on a last interconnect of the segment from the first voltage domain to the second voltage domain or the second voltage domain to the first voltage domain.
