Claim Text:
1. An apparatus comprising: a tail current source connected to a common node, the tail current source configured to source a predetermined current; a plurality of high-amplitude detection branches connected to the common node, each of the plurality of high-amplitude detection branches having an input node configured to receive via a multi-wire bus a respective element of a balanced-permutation modulation (PM) codeword having a predetermined number of high-amplitude values, and to divide the predetermined current among a number of conducting branches, the conducting branches being a subset of the plurality of high-amplitude detection branches, the conducting branches corresponding to high-amplitude detection branches receiving the predetermined number of high-amplitude values of the balanced-PM codeword.
