Abstract

A dynamic reference system for sense-amplifier is realised by utilising the dual signals generated at the respective output nodes of the two cascode circuits normally used to control the switches connecting the loads to the respective lines, in order to further control two imbalance transistors functionally connected between the switches and a source of polarisation current and essentially having different dimensions from each other, in order to superimpose an offset current on the current forced across the loads of the two lines of the input network so as to enable a discrimination even in the event of identical selected locations. The reference system is simple to construct and offers numerous advantages with respect to the static reference systems of the prior art. <IMAGE>
