Abstract:
1. A differential amplifier integrated circuit (IC) comprising: first and second transistors having respective first conduction terminals configured to be coupled to a first reference voltage, and second conduction terminals configured to receive a first differential current signal to be amplified; third and fourth transistors having respective first conduction terminals configured to be coupled to the first reference voltage and second conduction terminals configured to provide a second amplified differential current signal to a load, said third and fourth transistors each having a control terminal configured to be respectively coupled to the second conduction terminals configured of said first and second transistors to form current mirrors, said first and second transistors each having respective control terminals configured to be coupled to a common terminal; and at least one first resistive element and at least one second resistive element configured to be respectively coupled between the common terminal and the second conduction terminals of said first and the second transistors.
