Re: [期考] 類比積電
the following may be something wrong, i just express my opinion
assume perfect class AB and only one conduct
Vgsn+Vsgp=V'gsn or V'sgp only one conducts the current
(2I/knVov)^0.5+(2I/kpVov)^0.5=(2I/kn'Vov)^0.5 or (I/kpVov)^0.5
kn'Vov=1/(1/kn^0.5+1/kp^0.5)^2 ......
it's like a joke, I give up
I get it
the above is the idea of equivalent kn'Vov, after this result
Gm=4*kn'Vov*(W16/W12)
where 4 means total output current and W16/W12 means the current ration
Vov=bias voltage=delta V6 plus delta V8
XD maybe this is the wrong answer
※ 引述《sean51623 (千陽)》之銘言：
想問問各位有修課的同學
關於教授說要考的那題,還有HW12
大家都知道要怎麼推導嗎...?
想了蠻久也找過一些資料,不過還是沒什麼頭緒
加上老師上禮拜三之後有跟助教說不能教大家這題
所以希望會的同學能給一點hint,或是看大家能不能討論一下...
謝謝
