Abstract
Systems, apparatuses, and methods for performing offset correction for pseudo differential signaling are disclosed. An apparatus includes at least a sense amplifier and an offset correction circuit. The offset correction circuit generates an offset correction voltage by applying a positive or negative offset to a termination voltage. The offset correction circuit supplies the offset correction voltage to a negative input terminal of the sense amplifier. An input signal voltage is supplied to the positive input terminal of the sense amplifier. The sense amplifier generates an output based on a comparison of the voltages supplied to the positive and negative input terminals.
