The design features of the differential and differential difference current amplifiers for the sensor signal conversion with high intrinsic resistance

The article considers the design features of the analog converters of the sensor signals of the little-investigated subclass - the differential and differential difference current amplifiers (CA). The authors suggest the circuitry of the CA and its hybrid structures with the active negative voltage feedback, which enable (unlike the classical operational amplifiers) to realize the promising analog interfaces with new functional properties. The computer simulation results are given, which show the merits of active elements of this type for the tasks of control engineering, instrument making and communications.
