ABSTRACT:
An amplification and sampling device for multiplexed analog signals comprises a continuous chain of amplification elements, means for giving to each of said elements a gain selected from a predetermined set of values, sample-and-hold units for memorizing the amplified voltages available at the output of said elements, means for correcting the drift or noise voltage of the amplification chain and selection means for applying to the amplification chain the samples of the multiplexed analog signals or the voltages memorized in the sample-and-hold units, in accordance with the voltage level obtained at the output of the amplification chain as compared with reference voltages.
