ABSTRACT:
A differential amplifier having a first and second output terminals and receiving an input signal at an input terminal. The amplifier comprises a first amplifier having a first input connected to the input terminal, a second input and a first output connected together to the first output terminal, and a second output connected to the second output terminal, the first amplifier reproducing the input signal on the first output. The amplifier comprises a second amplifier having a first input receiving a reference signal and a second input connected to the output terminals by resistive elements and controlling the provision by the first amplifier on the second output of a signal such that the signals received at the first and second inputs of the second amplifier are equal.
