Two new current-mode Hamming neural networks are proposed in this paper.The first network consists of a current-mode template matching circuit and a fully interconnected current-mode Winner-Take-All(WTA)network.Simulation shows that it has high speed
high precision and low power dissipation. Based on the proposed network
another Hamming network which is composed of a current-mode template matching circuit and a voltage-mode WTA is also put forward.
