Abstract
A sense amplifier is disclosed that includes an amplifier circuit configured to receive, at an input, an input signal including an input level, the amplifier circuit configured to provide an amplified output signal including a gain with respect to the input level; and a feedback circuit coupled to receive the amplified output signal from the amplifier circuit, the feedback circuit configured to provide, at the input of the amplifier circuit, an adjusted version of the amplified output signal including a modified output magnitude based on common mode feedback.
Claims21
