Abstract
A sense amplifier that includes a sensing circuit, a first feedback circuit, and an output buffer. The first feedback circuit is coupled to an output of the sensing circuit and is configured in a feedback arrangement with the output buffer. The output of the sensing circuit provides an output signal having a first slew rate as the output signal transitions from a first logic state to a second logic state. The first feedback circuit may increase the slew rate of the output signal. The sense amplifier may also include a second feedback circuit coupled to the output of the sensing circuit and configured in a feedback arrangement with the output buffer. The second feedback circuit may increase a second slew rate of the output signal as the output signal transitions from the second logic state to the first logic state. The sense amplifier may be a current sense amplifier that may be used to sense the amount of current flowing through a nonvolatile memory circuit.
