Compensation of a winner take all circuit

The design and simulation results of a CMOS winner-take-all (WTA) circuit are presented. A 16-cell test circuit has been designed for intended implementation in an 0.18 /spl mu/m CMOS process. This paper describes the architecture and design issues related to a CMOS WTA circuit. Several design issues such as high resolution, high speed, low power consumption, compactness, and high input voltage range have been addressed. The proposed circuit has a compact configuration of complexity O(N) where N denotes input count. It seems to be very suitable, especially for charge-based applications where input vectors are generated by a set of charged capacitances
