Current mode circuits for programmable WTA neural network
In this article prototype AB class programmable synaptic connection and WTA circuits that set foundations for low power VLSI neural networks and other applications are proposed. The analysis of the circuits is given. A qualitative comparison of current consumption is made between standard A class and proposed AB class circuits. Layouts of the AB class transconductance programmable synaptic connection and 2-WTA circuits have been designed and then the prototype CMOS circuits have been manufactured and measured. Measured characteristics have been compared to simulated ones.
