A Low Voltage Current-Mode Maximum Winner Take All (WTA) Based On Flipped Voltage Follower (FVF)

This study demonstrates a new currentmode matcimum winner-take-all (Max WTA) circuit. High swing inputs and olrtput, and very low inputs and otttpttt voltage, and constant voltage for inputs, and occttpying small area are some of the most imporlant characleristics of this circuit. Flipped voltage follower (FVF) is used to achieve a high-performance and lowpower/ low-voltage circuit. Because of cascode configuration, the proposed circuit shows very good precision even for short channel MOSFETs. Simulation results based on 0.35mm CMOS technologt are also presented
