Abstract
A sense amplifier latch voltage waveform generator circuit provides an output voltage waveform which first increases to a first potential level, which is just below the threshold voltage of a field effect transistor, and subsequently increases with an ever-increasing slope over a useful voltage range. The generated voltage waveform is applied to the gate terminal of a latch field effect transistor, which is part of a sense amplifier circuit that includes a cross-coupled pair of field effect transistors whose sources are coupled to the drain of the latch transistor and whose drain terminals receive differential memory signals. The generator circuit consists essentially of an input gating transistor, an output stage having serially connected pull-up and pull-down transistors, and another similar feedback stage which includes a bootstrap capacitor. The bootstrap capacitor is coupled to the output stage.
