"Interpolative divider" was invented by Alexander Cherkassky (Hollis, N.H.).
According to the abstract* released by the U.S. Patent & Trademark Office: "An interpolative divider divides an input clock signal according to a divide ratio and supplies an output clock signal. An integer divider receives the input clock signal and supplies an integer divider output signal. A phase interpolator is coupled to the integer divider and delays the integer divider output signal according to a quantization error. The phase interpolator includes first and second current sources. The first current source turns on k unit current elements during a first part of a chargin...
