請大家幫忙,我那在 Cin//Rin 數值不知道怎麼求

Cin=1/jwC,缺少w不是算不出來嗎?

=============================================



Rs=100k ohm

Rin=100nF

Cin(in parallell connection with the input resistance)

Open-circuit voltage gain=100(V/V)

Rout=100 ohm

Question:(a)What's the overall voltage gain

         (b)If a voltage follower(Rin= infinite，A=1，Rout=0) is sandwiched

between，what is the overall voltage gain

============================================================================
the overall voltage gain=Vs/Vo=(Vs/Vi)*(Vi/Vo)

但是就卡在電容與電阻串聯不知道怎麼解

(b)的答案是不是同(a)?

謝謝大家回答
