Abstract :
Multibit delta-sigma conversion requires an internal DAC so extraordinarily accurate that signal processing to move DAC hardware-mismatch error outside the signal band appears necessary. Here the error-shaping DACs reported previously are shown mathematically to be special cases of a general architecture convenient for analysis and simulation
