Abstract

Experimental results and computer simulation of multi-stage composite transistors are presented. To study the volt - ampere characteristics of multistage composite transistors, a dialogue computer simulation program, the Delphi programming environment, has been developed. It is shown that the proposed multistage composite transistors can improve manufacturability in its industrial production. It is shown that multistage homostructure transistors according to the Darlington and Shiklai circuits operate stably at collector-emitter voltages five times higher than in the case of individual transistors. The power dissipated on the collector is 3 times higher than the rated value of the maximum permissible power of the composite transistors. It is established that the efficiency of the method of stabilizing the emitter current of a three-link homostructure transistor is 7 times higher in voltage and three orders of magnitude higher in temperature compared to a conventional composite transistor. The proposed homostructure transistors are designed to operate in terminal stages of power amplifiers, radio transmitting devices, electronic equipment of industrial and automotive electronics.
