3F推:如果覺得razavi書難懂, 你看 D.Johns的書應該會哭出來吧12/07 01:15
1F推:source follower 是當做 level shift 抬共模用的09/10 22:21
3F推:你把 differential vin 都接到 Vcm (AD8031) 看看09/03 00:22
4F→:如果 0V differential input的時候 output 還是會跳動09/03 00:22
5F→:那就是電路的ENOB就只有 5.3b09/03 00:22
6F→:不然就是去其他實驗室借高檔點的Signal generator 或AWG09/03 00:23
7F→:直接輸出 differential signal, 減少量測變數09/03 00:24
1F推: "+"號放錯位置03/21 15:13
1F推: xR1 N_1 N_2 rpol l=xu w=yu x,y自己算12/19 16:07
3F推:把inv裡的p/nmos L/W 設成property 這樣就可以symbol填值08/07 23:22
4F→: M也可以設成property 或者是用陣列表示 <2:0> = M=308/07 23:23
2F推:請愛用 fft 直接對output取點做fft07/31 20:50
1F推:如果你是初學者 把"Understanding Delta-Sigma" 這本書的07/31 23:53
2F→:架構選一個照抄就好了 不然光搞懂整個flow你就有得搞了07/31 23:53
2F推:noise-shape是基本要做到 OSR要高 digital filter好做05/10 20:37
3F→:另外注意OPAMP offset cancellation的方法05/10 20:37
1F推:負回授gain > 正回授gain 避免震盪 這樣懂了吧05/09 12:30
