Abstract
In certain aspects, a regenerative stage of a sense amplifier includes a first inverter having an input and an output, and a second inverter having an input and an output. The regenerative stage also includes a third inverter having an input, an output coupled to the input of the second inverter, a first supply terminal coupled to a supply rail, and a second supply terminal coupled to the output of the first inverter. The regenerative stage further includes a fourth inverter having an input, an output coupled to the input of the first inverter, a first supply terminal coupled to the supply rail, and a second supply terminal coupled to the output of the second inverter.
