Abstract
An integrated circuit comprising a balanced differential amplifier. The balanced differential amplifier has a first single-ended differential amplifier coupled at a first negative differential input terminal to a first input signal through a feedback network also coupled to an output terminal of the first amplifier. The first amplifier is also coupled at a first positive differential input terminal to a second input signal through a first resistor and to a reference voltage. The balanced differential amplifier also has a second single-ended differential amplifier coupled at a second negative differential input terminal to the second input signal through a second feedback network also coupled to an output terminal of the second amplifier. The second amplifier is also coupled at a second positive differential input terminal to the first input signal through a second resistor and to the reference voltage.
