ABSTRACT:
The present invention relates to a differential amplifier with differential outputs comprising a reference input, a signal input, a first (2) and a second (3) low-pass filter respectively connected with a differential output and with a comparator input (4), the comparator output being connected with the reference input of the amplifier in order to form a regulation loop which compensates for the d.c. level variations of the signal applied to the signal input and which servo-controls the d.c. level difference of the outputs to a value approaching zero. The invention applies to integrated circuits with differential amplifiers.
