Baza elektrodidagi tok rekombinatsiyasi tashkil etuvchi Ibrek dan tashqari , ΠΠning injeksiyalangan kovaklar toki Ier va ΠΠning xususiy toki IΠ0 dan tashkil topgan.Baza tokining rekombinatsiyasi IΠΠ ΠΠ va injeksiya IΠΡ tashkil etuvchilar yoβnalishlari bir xil.Agar ΠΠga qoyilgan kuchlanish teskari yonalishda bolsa uning xususiy toki IΠ0 teskari yonalgan boladi. Tok boβyicha kata kuchaytirish koeffitsiyentini taminlovchi sxema bipolyar transistor Umumiy emmiter sxemada ulangan. Ushbu sxemada umumiy elektrod bolib emmiter, kirish toki boβlib baza toki, chiqish toki boβlib esa kollektor toki xizmat qiladi. Download 224.8 Kb. Do'stlaringiz bilan baham: |
