Precharged bit decoder and sense amplifier with integrated latch usable in pipelined memories

摘要

The amplifier device includes a bistable differential amplifier, a dual-slope circuit, and pre-charge transistors (34,35). The dual slope circuit enables sensing of differential voltage by the bistable differential amplifier. The precharge transistors precharge at least the dual-slope circuit and the amplifier inputs in sequence. A latch circuit combined with the dual slope circuit causes latching of outputs of the differential amplifier. The precharge transistors are also reset the latch circuit.
