1^F推kk123: 分壓比例代表不同的VOUT 設定值，所以noise 被放大比例就10/20 09:02

2^F→kk123: 不一樣，VOUT設定越高，output noise 越大10/20 09:02

3^F推kk123: noise 有 vn1 vn2 這兩項跟電阻分壓比都有關10/20 12:12

6^F推kk123: noise 的公式怪怪的，AMP 如果是 error amp的話，應該會乘10/20 16:33

7^F→kk123: 上電阻分壓比例10/20 16:33

9^F推kk123: M1&M2 可以換 Native NMOS or Dep. NMOS 嗎？06/11 10:31

10^F推kk123: 如果都不能換的話，那就輸入電壓用 pmos source follow 把06/11 10:33

11^F→kk123: 電壓墊高吧06/11 10:33
