Abstract :
Resistive networks can be used as spatial filters to average the random errors in arrays of analog cells, specifically for decreasing the offsets in flash and folding A/D converters. In this communication the critical conditions the averaging networks have to satisfy are pointed out and the optimal topology, order, and parameters of the resistive grids are identified for each of the two ADC architectures.
