Abstract
A linear differential amplifier with improved voltage swing is disclosed. The linear differential amplifier corrects for an error voltage inherent in differential pair amplifiers, without hindering the available voltage swing, and thus, is particularly suited for low-voltage applications. The differential amplifier includes an input differential amplifier for receiving an input voltage difference to be amplified; a distortion correction differential amplifier for producing an error correction amount; and an output differential amplifier for receiving the input voltage difference and the error correction amount, amplifying the input voltage difference to produce an output voltage, and correcting the output voltage in accordance with the error correction amount. Also disclosed is a method for improving available voltage swing of a differential amplifier when amplifying an input voltage difference.
