IMPROVED ERROR TABLE COMPENSATION OF A D CONVERTERS USING PSEUDORANDOM CALIBRATION SIGNALS/

A previously published technique using sinusoidal calibration signals to generate error tables for linearising A/D convertors suffers from l imited compensation performance due to incomplete error table coverage . The authors show that better coverage and improved compensation may be achieved by using pseudorandom calibration signals. The technique i s illustrated by using state-space error tables to reduce the nonlinea r distortion of an A/D convertor sampler model representing input depe ndent timing jitter.
