CMOS Current Mode Winner-Take-All Circuit with Distributed Hysteresis

An analogue-VLSI winner-take-all circuit is enhanced through the addition of hysteretic feedback that emphasizes the spatial locality of competing signals using a resistive network. This circuit has application to tasks in areas such as image processing, in which inputs are not stationary with respect to the circuit array. Introduction Analogue VLSI circuits facilitate the implementation of low...
