Advances on Multiplexer Synthesis: The Herringbone Topology

Current multiplexer synthesis methods have proven to be a reliable tool to start and speed up the design of such a challenging network. However, most of these current methods have focused their attention on star junction multiplexers, which may bring many advantages if compared to other topologies, but may not be convenient in some cases as they do not consider the possible routing and actual connections throughout a multiplexer. This work presents a multiplexer synthesis methodology taking into account the existence of phase shifters or transmission lines along the multiplexer, such as the well-known Herringbone topology.
