A Low-Complexity current-mode WTA circuit based on CMOS Quasi-FG Inverters

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.
