Abstract
A low-voltage CMOS current-mode Winner take all and looser take all circuits are designed in 0.35 µm standard CMOS technology.Simulation results using HSPICE that verify the functionality of circuit with 1.5 V supply are presented. The circuit can find application in the implementation of Fuzzy and Neural Network circuits.
Highlights
Winner-Take-All (WTA) and Looser-Take-All (LTA) circuits are the analog important and major function building blocks
WTA and LTA can be extensively categorized as the current mode and voltage mode structure
In addition existing voltage mode structures are larger than current mode structures in hardware and area
Summary
Winner-Take-All (WTA) and Looser-Take-All (LTA) circuits are the analog important and major function building blocks. The function of WTA and LTA circuits identify the largest and the smallest input variable, respectively, and restrains the remaining ones. WTA and LTA can be extensively categorized as the current mode and voltage mode structure. Using current mode analog circuit design has received wide attention due to the supply voltage scaling down and their potential of lower power consumption [1]-[3]. In this paper we proposed a novel current mode WTA and LTA. There are several structures of current mode WTA and LTA circuit proposed on the literature [4]-[6].
