Offset compensation for sense amplifiers

摘要

A sense amplifier (100) having compensation circuitry is described. The compensation circuitry includes at least one pair of compensation transistors (P01, P02). When compensation is desired, one or a combination of the bulk of the at least one pair of compensation transistors (P01, P02) is provided with one or a combination of compensation voltages. A BIST is carried out for a plurality of sense amplifiers (100) which are grouped and re-offset according to the results of the BIST.
