Abstract

A sense amplifier includes a reference voltage generator for generating a reference output voltage and a core output voltage generator for generating a core output voltage. The core output voltage generator includes a core front-end stage and a core back-end stage or includes a plurality of amplifier transistors each conducting a portion of a core current through a current conducting device such as core cell. The sizes and/or connections of transistors of such components result in high voltage swing and thus high sensitivity of the sense amplifier.
