Abstract
A sense amplifier for fast and reliable sensing of a small voltage differential is accomplished by the integration of a latch which uses regenerative feedback. Complementary devices are used within the sense amplifier to modify its configuration from an amplifier to a latch. The integration of the latch for gain allows the use of a single-ended sense amplifier section, as opposed to requiring a double-ended design for level shifting and symmetrical sensing of `0` and `1`. The output is a pair of full-rail complementary signals that can be directly used by standard CMOS logic downstream.
