LOW-VOLTAGE DIFFERENTIAL AMPLIFIER

摘要

A low-voltage differential amplifier circuit is disclosed. The low-voltage differential amplifier circuit includes a first differential amplifier, a second differential amplifier and a summing circuit. The first differential amplifier receives a pair of differential input signals to generate a first output. The second differential amplifier receives the same pair of differential input signals to generate a second output. The summing circuit sums the first output of the first differential amplifier and the second output of the second differential amplifier to provide a common output.
