Abstract
The differential input stage of a sense amplifier is provided with a positive feedback for introducing a predefinable hysteresis that will prevent spurious transitions of the output of the sense amplifier, enhancing noise immunity. The positive feedback is realized by employing an inverting amplifying stage, which will introduce an hysteresis on one of the two switching phases. The thresholds of the sense amplifier may be made symmetric by modifying the area ratio of the load transistors.
