mosfet gm 在 Re: [問題] gm的實際意義- 看板Electronics - 批踢踢實業坊 的推薦與評價
※ 引述《newwrite (jikk)》之銘言:
: 最近念到了電子學中轉導的部分 想請教一下
: 1.在MOS和BJT中 都要我們算gm
: 請問一下gm的大小代表了元件的何種物理特性呢?
在輸入端施加一個小信號電壓時,輸出端會產生小信號電流,
而gm的定義便是輸出端小信號電流除上其對應的輸入端小信號電壓。
直覺來想gm越大,亦即同樣的輸入小信號電壓可以產生較多的小信號電流在輸出端,
而較大的輸出端小信號電流再乘上輸出端等效電阻,便可得到較大的輸出端電壓
因此電壓增益提升。
另外,一個元件的gm值較大,則此元件也可以達到較高的操作速度(電流單增益頻率高)。
你可以想成是因為小信號電流比較大,在高頻率時充放電電容較容易。
: 2.電路中的短路轉導Gm
: 在實際電路上的意義又為何呢?
: Gm大一點好還是小一點對整體電路好呢
Gm的概念只是把整個電路當成一個黑盒子,而這個黑盒子的等效gm就定義為Gm。
同樣的,Gm越大對整體電路的好處會比較多。
: 謝謝!
