ABSTRACT:
A high performance "two stage" (or cascading) Self-resetting CMOS (SRCMOS) amplifier where the 2nd stage amplifier is self-timed off of the 1st stage. Also, the SRCMOS nature of this amplifier eliminates the need for additional reset clock signals. The net affect of this invention is that the sensing action of a SRAM cell can start sooner (relative to a single stage sensing scheme) thereby delivering the data to the outputs sooner while providing greater noise immunity when compared to traditional sense amplifiers.
