Abstract

A method for the enhancement of dynamic performance of scan converter-based transient digitizers is proposed. First, a technique for discriminating the best diode target region is illustrated. Then, by considering the digitized charge distribution on the target as a digital image, a filtering algorithm capable of recovering trace discontinuities is shown. Results of tests carried out on an actual digitizer are reported
