Engineering Physics Annotation << Back COMPLEMENTARY CASCODE CURRENT SOURCE KH.K. ARIPOV, Z.KH. ARIPOVA, SH.T. TOSHMATOV, KH.KH. KHAYRULLAYEV The article discusses the developed complementary cascode current source using light-emitting diodes devices infocommunication systems for transmitting information and electrical lighting. It is shown that the performance on efficiency coefficient of the proposed composite cascode current source with a change in supply voltage and load resistance in the wide band is more than twice the efficiency of the closest analogue. Keywords: stable current generator, light emitting diode, bipolar transistor, cascode, injection-voltaic transistor, complete transistor. DOI: 10.25791/infizik.11.2021.1233 Pp. 03-08.
