PERFORMANCE ANALYSIS OF SINGLE-ELECTRON WINNER-TAKE-ALL NETWORK CIRCUITS

In this paper new single-electron tunneling (SET) based circuits are proposed: SET winner-take-all (WTA) networks. Two network configurations have been studied: a fully interconnected architecture and a lateral inhibition architecture. Their performance was evaluated using a dot pattern recognition task. Critical aspects in SET-based circuits were taken into account, such as cotunnelling, temperature dependence and background charges. Power consumption and area estimations (critical for GSI and TSI realizations) were also taken into account.
