Abstract
A new solution for a non-conventional loser-take-all (LTA) circuit is proposed in the paper. The circuit possesses several inverting and non-inverting input terminals and an additional current output, which increases its versatility and allows simplifying its possible applications. In order to show its usefulness and versatility, several new applications of the proposed LTA have also been developed, including a simple digital-to-analog converter, an n-bit programmable adder/summer, a chopper modulator and a precision rectifier. The LTA has been designed and fabricated with a 0.35 (Formula presented.) CMOS I3T25 AMIS process, exploiting the recently proposed bulk-driven quasi-floating-gate technique. The LTA circuit operates from 1 V supply and dissipates 74 (Formula presented.) of power. The simulations performed in Cadence environment and the measurements of a real chip confirm the attractive features of the proposed LTA.
