本文提出了一种新的GaAs-(P~+n-i-Pn_+)结构的恒流源二极管,论述了它在高反编压下输出恒定电流的原理,从材料和工艺方面论述了它的可行性,同时,给出了输出恒定电流的近似表示式。
In this paper, a new constant current source diode with GaAs- (P ~ + ni-Pn_ +) structure is proposed. Its principle of outputting constant current under high back-pressure is discussed. Its feasibility is discussed from the aspects of material and process At the same time, an approximate expression of the output constant current is given.
