Abstract

Abstract Translated from French L'invention concerne les amplificateurs différentiels de courant. Pour obtenir une amplification d'une différence de deux courants I1 et I2 avec une bonne réjection de mode commun, on fait passer les courants I1 et I2 alternativement dans deux résistances égales R1 et R2 et la chute de tension différentielle R1 et dans R2 est amplifiée par un amplificateur de tension. The invention relates to differential current amplifiers. To obtain an amplification of a difference of two currents I1 and I2 with good common mode rejection, the currents I1 and I2 are passed alternately through two equal resistors R1 and R2 and the differential voltage drop R1 and in R2 is amplified by a voltage amplifier.
