兩個問題:
1. 你要放大的輸入信號頻率是1MHz嗎?
2. 圖中穩壓管的穩壓值是3.3V嗎?

我看了看你的圖,修改了一下,把輸入頻率改為1KHz, 輸出能正常跟隨輸入信號,如下圖所示:

500) {this.resized=true; this.width=500; this.alt='這是一張縮略圖，點擊可放大。\n按住CTRL，滾動鼠標滾輪可自由縮放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/49/1168921397.gif');}" onmousewheel="return imgzoom(this);">

Domono:謝謝你的回復!里面的那個是3.3V的ZENNER,頻率1K就可以了.不過我放的是V_Pulse,提示有兩個error:> dcexecution time= 0.0781 sec.> tr (tend 100u,tstep 0.1u*** ERROR "ALG_NO_SOLUTION" *** Cannot find nonlinear system solution.*** ERROR "ALG_ITERATIONS" *** Too many iterationsPartial results at time=25.6f were written to the initial point "tr".execution time= 0.109 sec.messages given: 2 errors>pl (plaction replaceOpening connection to Cosmos Scope...Loading plotfile(s) into Cosmos Scope...execution time= 0.0156 sec.>請問你放的是什么信號源,有空能指教一下么??

tstep 太大了,設置為1n. 信號源就是用你原來的,只是將width設置為0.5m, period 設置為1m. 另外,zener的model->vzt參數設置為3.3. ic參數設置為undef. 你這樣在試試看吧.
