你的問題有點籠統 @@ 如果是高頻響應的話 必須考慮所有電晶體的parasitic電容 然後判斷出RC值較大的節點 找出電路極點(pole) 也必須觀察出電路的零點(zero) 然後畫magnitude response時 通過零點後會+20dB/decade 極點後會-20dB/decade phase response的話 通過零點會逐漸+180度...

簡單來講,20dB是一種定義,也就是20log(x)=20 -->x=10 先講amplitude 而FH(S)=(1-s/10^5)/[(1- s/10^4)(1- s/(4*10^4))] 將FH(s)取log之後,乘除就變成log(FH(s))=(DC gain)*(log(Z1-s)-log(P1-s)-log(P2-s)) 當s=0時FH(s)=(DC gain) S>...
