Compact four-terminal TCOIL

Abstract:

The present embodiments relate generally to data communications, and more particularly to systems including high-speed serializer-deserializer circuits having TCOILs. One or more embodiments are directed to a four-terminal TCOIL structure that consumes the same amount of area on a chip as a traditional three-terminal structure, while providing more bandwidth and less reflection and group delay variation.
