ABSTRACT:
A sense amplifier for a computer memory includes a plural stage differential amplifier. The first stage of the differential amplifier includes an input emitter follower connected to the input of the first stage differential pair. A negative feedback loop is connected around the first stage. The negative feedback loop enhances the response characteristic of the amplifier. Circuit means are also provided which enables the selective steering of energizing current through or away from the second stage of the differential amplifier to provide for the selective blocking of the output of the sense amplifier.
