Abstract

Многоканальное фотоприемное устройство, содержащее операционный усилитель, в цепь отрицательной обратной связи которого включен резистор, n вентильных фотоэлементов, первые одноименные выходы которых объединены и подключены к инвертирующему входу операционного усилителя, а вторые выходы соединены соответственно с первыми выводами n коммутационных элементов, вторые выводы которых подключены к общей шине устройства, а управляющие входы соединены с соответствующими выходами дешифратора, отличающееся тем, что, с целью повышения быстродействия и надежности, в него дополнительно введены вторые n коммутационные элементы, первые выводы которых подключены соответственно к первым выводам первых n коммутационных элементов, вторые выводы объединены и подключены к неинвертирующему входу операционного усилителя, а управляющие входы соединены с соответствующими управляющими входами первых n коммутационных элементов.A multichannel photodetector device containing an operational amplifier, whose negative feedback circuit includes a resistor, n valve photocells, whose first like outputs are combined and connected to the inverting input of the operational amplifier, and the second outputs are connected respectively to the first terminals of the n switching elements, the second terminals of which are connected to the common bus device, and the control inputs are connected to the corresponding outputs of the decoder, characterized in that, in order to increase the speed Action and reliability, it additionally introduces the second n switching elements, the first terminals of which are connected respectively to the first terminals of the first n switching elements, the second terminals are combined and connected to the non-inverting input of the operational amplifier, and the control inputs are connected to the corresponding control inputs of the first n switching elements.
