   The basic shortages of the conventional circuit of the preamplifier for a photoreceiving device on the basis of CdHgTe photoresistor are considered in a paper. The various variants of non-tradicional preamplifiers based on use of the differential amplifier with the interior feed-back "Elan-1B" are offered. The basic parameters of the developed microassemblies for preamplifiers are represented.
