Abstract :
A high-performance CMOS winner-take-all circuit based on the differential flipped voltage follower is introduced. Simulations demonstrate the potential of the circuit to operate at very high speed, with high precision even for close input values and with low supply voltages. Experimental verification of the circuit is provided in a 0.5-mum CMOS technology.
