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 (千阳)》之铭言：
想问问各位有修课的同学
关于教授说要考的那题,还有HW12
大家都知道要怎么推导吗...?
想了蛮久也找过一些资料,不过还是没什么头绪
加上老师上礼拜三之后有跟助教说不能教大家这题
所以希望会的同学能给一点hint,或是看大家能不能讨论一下...
谢谢
