Question

+VDD IBAS CV +VDD Q ON VGG - Vo V Q2 lp RL vo -Vss

I want to know how I can get the gain equation. Av=(RL)/(RL+Rout)

Thanks

Answer 1

Small signal voltage goin Ava 22 Vo = output voltage ๔. Vi = input voltage Ri R2 + Rout Ava Rout- (here transistors are matched] ท, พ- 35 gmppu gnp ampe gone * * (55 gup ทง - 9mn Im Iman ง40 RL A = RL + สั ย

We know that, Simal signal voltage gain Av = RL/(RL +Rout).
