我用MOS管做的RCC电路,波形如下,请大家提提意见

我用MOS管做的RCC电路,波形如下,请大家提提意见,MOS管源极(S极)到地有一个0.4Ω的小电阻限流看波形上,Vgs大约在13V左右.
1、Vgs波形

2、Vds波形,衰减了100倍
500) {this.resized=true; this.width=500; this.alt='这是一张缩略图，点击可放大。\n按住CTRL，滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/64/2487901207793779.jpg?x-oss-process=image/watermark,g_center,image_YXJ0aWNsZS9wdWJsaWMvd2F0ZXJtYXJrLnBuZz94LW9zcy1wcm9jZXNzPWltYWdlL3Jlc2l6ZSxQXzQwCg,t_20');}" onmousewheel="return imgzoom(this);">
3、下面的源极到地的波形,电压好像很低
