Abstract
A tunable/adaptive feedthrough-error cancelation technique for switched-current circuits is presented. A comparison, based on measurements from silicon prototypes designed with the same technology and equal geometries, shows an improvement of more than one order of magnitude as compared to the conventional dummy-switch technique. Robustness against local process or switch-geometry variations has been observed, ensuring global adaptability of several track-and-hold stages.
