In this paper we present two analog VLSI circuits thatimplement current mode winner-take-all (WTA) networks with lateralexcitation. We describe their principles of operation and comparetheir performance to previously proposed circuits. The desirableproperties of these circuits, namely compactness, low power consumption,collective processing and robustness to noisy inputs make themideal for system level integration in analog VLSI neuromorphicsystems. As application example, we implemented a circuit thatemploys an adaptive photoreceptor array as the input stage tothe WTA network for edge enhancement.
