ABSTRACT:
A self-adjusting winner lineup amplifier comprising signal control sections which level-control comparison signals (Ci) from word weighted comparators of a memory area, a self-adjusting distance amplifying section corresponding to the respective rows in the memory area which outputs the level-controlled comparison signals (Ci) as distance amplified signals (LAi), a feedback generating section which inputs a self-adjusting voltage (Fa) common to the distance amplifying sections, and a voltage follower which converts its input voltage (min{Ci}; a minimum value of Ci) into a feedback voltage (F) to supply the feedback voltage (F) in parallel and with strong driving current to the signal control sections, wherein amplification characteristics of the distance amplifying section are self-adjusted by a comparison signal (Cwin) of a winner row, and the signal control sections lead the comparison signal (Cwin) into the range of a maximum gain area of the distance amplifying section.
