ABSTRACT:
Positive feedback increases switching speeds and negative feedback prevents the voltage at the inputs from varying too far in a sense amplifier used to sense voltage differentials on bit lines or data lines of semiconductor memories, or elsewhere. Switching speeds improve without increased current consumption.
