Abstract :
In this paper we present a Winner-Take-All (WTA) circuit realized using current-mode circuit design techniques. The operation of the WTA is based on current comparators and current mirrors. Speed and precision is determined primarily by the characteristics of the current mirror used. Using special current mirrors, resolutions below 1% and settling times below 100 ns were simulated. The circuit remains operative with reasonable speed and precision for an input-signal range wider than two decades. It requires current input signals and provides voltage output signals
