標題[問題]ADS2005元件的noise figure問題
時間Wed Jul 4 00:23:31 2007
請為大家..
我想用ADS2005去模擬一顆Bjt的NF
電路部份應該沒問題..但是我去模擬後出現錯誤訊息如下
varning detected by hpeesofsim during SP analysis `SP1'.
The simulation temperature (25.0 C) is not the same as the IEEE standard
noise temperature (290 K or 16.85 C) in the noise analysis `SP1'.
If the simulation temperature is not equal to the IEEE standard temperature,
then the loss and the noise figure will not agree for a passive circuit.
The `Temp' parameter on the Options item can be set to 16.85 C to
eliminate this warning message.
請問message所提的溫度要去哪裡設定呢??
裡頭所提的option是在哪裡呢??我怎麼找不到可以setting的地方
謝謝大家的幫忙...
RF菜鳥敬上

1F：推 avexkeiko:你可以任選一個模擬的type，例如：AC、220.134.101.136 07/04 00:36
2F：→ avexkeiko:DC、HB、SP...等，在左邊就會有option可220.134.101.136 07/04 00:38
3F：→ avexkeiko:拉出來，裡面有溫度的選項220.134.101.136 07/04 00:39
4F：→ pttnewer:以解決謝謝大大125.224.185.208 07/04 01:03
