Patent attributes
An amplifier comprises: first and second supply terminals intended to receive a DC supply voltage; a first branch coupled between the first and second supply terminals and including a first terminal of application of a differential signal to be amplified; a second branch coupled between the first and second supply terminals and including a second terminal of application of the differential signal to be amplified; a third branch coupled between the first and second supply terminals and including a first amplifier having an input terminal connected to the second branch and having an output terminal configured to be coupled to a load, and a measurement element configured to measure a current in the third branch; and a fourth branch coupled between the first and second supply terminals and including a second amplifier having an input terminal connected to the first branch, and a copying element configured to copy the current measured in the third branch.
