Olingan natijalarga ishlov berish:
1-jadval asosida olingan o‘lchash natijalari asosida uzatish xarakteristikasi oilasi (ya’ni USI=const bo‘lganda, IS=f(UZI)) va chiqish xarakteristikalari oilasi (ya’ni UZI=const bo‘lganda, IS=f(USI)) bog‘liklik grafiklar chiziladi.
− Xarakteristika tigkligini hisoblash:
U = const bo‘lganda, ; bunda, va
SI
;
USI =2V bo‘lganda, ;
; .
− Ichki (differensial) qarshilikni hisoblash:
U = const bo‘lganda, ;
ZI
UZI =-0,5V bo‘lganda,
;
;
− Kuchlanish bo‘yicha kuchaytirish koeffitsientini hisoblash:
I =const bo‘lganda, 𝜇 = ∆𝑈𝑆𝐼 yoki SR ;
S i ∆𝑈𝑍𝐼
SRi =789,26*0,0011=0,868;
XULOSA
Biz ushbu labaratoriya ishida tranzistor ulashni uni ishlatishni bazi parametrlarini o`rgandik .Labaratoriyadan shuni xulosa qilishimiz mumkunki Uzi ortib borgani sari
Is o`zgarishi kamayib borar ekan Usi ortib borgan sari ham
Is o`zgarishi kamayib borar ekan
