Abstract
A dynamic tap weight generator circuit includes a clock generator circuit having a first output and a second output. There is a current interpolator circuit coupled to a first current source and a second current source and to the first and second outputs of the clock generator circuit and operative to provide a first output and a second output providing a differential output current between a current of the first current source and a current of the second current source across a symbol transmission interval. A 2:1 current multiplexer is coupled to a first and second outputs of the current interpolator circuit. A tap weight driver is coupled to an output of the 2:1 current multiplexer and configured is to dynamically adjust a tap weight of an equalizer dynamically during each clock cycle of the clock generator.
