摘要： In at least one embodiment, a differential amplifier including first and second current transfer systems, a current difference producing system, and a feedback network circuit is provided. The first current transfer system generates a first differential current signal. The second current transfer system generates a second differential current signal. The current difference producing system receives the first differential current signal and the second differential current signal and generates a voltage difference signal that is indicative of a difference between a first current signal and a second current signal. The feedback network circuit converts the voltage difference signal into at least two converted current signals and provides the at least two converted current signals to one of the first and second current transfer systems or the current difference producing system to minimize the difference between the first current signal and the second current signal.
