Abstract

See full text

Methods and apparatuses for high rotation rate low I/O count phase interpolation are disclosed, including techniques to reduce redundant phase interpolation coding and method steps by modifying phase mapping and generation with pluralities of amplifiers. I/O reduction count is achieved while maintaining resolution and allowing scalability in phase interpolation. Control circuits include techniques to interpolate phases at a high rotation rate while reducing discontinuities and risk for logic hazards.
