Abstract
An amplifier circuit comprising an amplifier (1) having an input (11) which receives an electric signal comprising an intermittent useful signal component V.sub.U and an undesired spurious component V.sub.D and an input (12) of opposite sign to that of the input (11). The output signal of a circuit (2) for the compensation of the spurious component is applied to amplifier input. The circuit (2) comprises a comparator (20) for comparing the undesired component, taken from the output of the amplifier (1), with a threshold value, a counter (21) which is incremented or decremented depending on the result of the comparisons and in the rhythm of a clock circuit (22), and a digital-to-analog converter (23) coupled to the output of the counter (21) to supply the signal for the compensation of the unwanted component to the input (12).
