A Low-Complexity current-mode WTA circuit based on CMOS Quasi-FG InvertersKeywords: winner-take-all, neural networks, analog circuits. Abstract: in this paper, a low-complexity current-mode winner-take-all circuit (wta) of o (n) complexity with logical outputs is presented. the proposed approach employs a quasi-fg inverter as the key element for current integration and the computing of the winning cell. the design was implemented in a double-poly, three metal layers, 0.5μm cmos technology. the circuit exhibits a good accuracy-speed tradeoff when compared to other reported wta architectures.
