Multi-level signal transmitter and method thereof

Abstract

A multi-level signal transmitter includes an encoder figured to receive an input data and output a plurality of logical signal sets, each of said plurality of logical signal sets comprising a plurality of logical signals; and a plurality of tree-structured drivers configured to receive said plurality of logical signal sets, respectively, and jointly establish an output voltage at an output node, wherein each of said tree-structure drivers comprises a plurality of inverters configured to receive said plurality of logical signals of its respective logical signal set and jointly establish a joint voltage at a bifurcation node via coupling to the bifurcation node through a plurality of first-level weighting resistors, and a second-level weighting resistor configured to couple the bifurcation node to the output node.
