Abstract[English]
A multiply-accumulate successive approximation (MASAR) column is provided. The MASAR column includes a plurality of MASAR cells, each including a multiplier configured to perform digital multiplication between an input activation received to an input and an operand to compute a result, and a unit capacitor configured to store the result as analog charge. The MASAR column further includes digital logic configured to perform analog summation of the analog charge of the unit capacitors of the plurality of MASAR cells to determine a digital output of the multiplication.[French]
Est divulguée une colonne d'approximation successive par multiplication-accumulation (MASAR). La colonne MASAR comprend une pluralité de cellules MASAR comprenant chacune un multiplicateur configuré pour effectuer une multiplication numérique entre une activation d'entrée reçue à une entrée et un opérande pour calculer un résultat, et un condensateur unitaire configuré pour stocker le résultat en tant que charge analogique. La colonne MASAR comprend en outre une logique numérique configurée pour effectuer une sommation analogique de la charge analogique des condensateurs unitaires de la pluralité de cellules MASAR afin de déterminer une sortie numérique de la multiplication.
