Pspice(AC SWEEP)

電子電路

slide4
雜訊分析

1、Ntype(device):表示某個元件的雜訊值

type表示雜訊種類 device表示元件名稱

例:NTOT(R1)表示R1的總雜訊值(total noise)

2、整個電路的總雜訊:

(1)輸出電壓總和雜訊值V(ONOISE)

(2)輸入電壓總和雜訊值V(INOISE)

(3)輸入電流總和雜訊值I(INOISE)

slide6
計算掃描點數

頻率上使用:

總掃描點數=(log(結束頻率)-log(開始頻率))

*(掃描點數+1)

時間軸或其他使用:

[(結束值-起始值)/遞增值]+1=掃描點數

X軸的值 Y軸
