Abstract
A read amplifier formed of a load component (L), a differential amplifier component (DIFF), a compensation transistor (N6), a switching transistor (P1) connected between a supply voltage (V.sub.DD) and the load component (L). The pre-loading potential of the read amplifier at its outputs LA, LA is about 2.5 volts. During the pre-loading phase, the two supply voltages (V.sub.DD, V.sub.22 =ground) are disconnected and the pre-loading potential is established by compensation of capacitances at the outputs LA, LA which results in an improved read amplifier.
