从I-V curve角度,我们一般收Id-Vg curve多Scan Vg<0那一段就可以评估其GIDL特性。 HCI (热载流子注入效应):Drain端电压不变时,如果沟道有效长度Leff变小,则沟道电场强度增加,从源端过来的电子被加速碰撞晶格产生更多的电子空穴对,发生链式反应,新产生的电子被Drain端吸收成为Id, 新产生的空穴则在栅极电场的作用...
Abstract:One evaluation method about double hump phenomenon is introduced in this paper.Through curvilinear regre-ssion analysis in Id-Vg curve,the degree of double-hump is designated on a numerical scale.Logically,the correlation of implant′s ion concentration and double hump can be studied with...
範例一:extract name="取出參數的名稱" y.val from curve(x軸變量,y軸變量) where x.val=X 代表:我要取某點的y座標值,該點在vgate-idrain圖的曲線上(舉例),x座標是X,稱此y座標值作為"變數的名稱" 範例二:extract name="取出參數的名稱" x.val from curve(怎樣運算(x軸變量),怎樣運算(y軸變量)) ...
To model a tabulated diode, set the Model body diode parameter to Tabulated I-V curve. This figure shows the implementation of the tabulated diode option: When choosing this parameterization, you must provide the data for the forward bias only. The block implements the diode using a smooth int...

由於續流二極體的逆向恢復電流而增加,在此區間,MOSFET 的 VDS電壓保持等於 VDD電壓,Gate電壓 VG 增加會 與從0 到 t1 的時間段的VG幾乎相同,可由公式(1)所示. (3) t2 至 t3(MOSFET 正在切換) 隨著續流二極體的逆向恢復電流降至為零,MOSFET 的ID電流達到負載電流IO,然後,Gate電壓下降到 VGS1,此時ID電流...

in the linear region, while IDSATis the measured drain current with the device biased in the saturation region. VTHand GMcan be determined using either constant current or extrapolation methods. In the extrapolation method, the VTHis determined from the maximum slope of the IDSvs. VGScurve. ...
•Vg远大于平带电压、Vd=0V时,沟道表面积累电子(由 N+区提供),电容最大(Cox) •Vd增大,表面逐渐耗尽,耗尽层同时向下向右推移 •一定电压下,沟道全耗尽,电容达到最低 •当Vg电压不够高,过程同上。Vd=0V时达不到积累, 处于耗尽状态,最大电容变小 4 RuHuang,IME,PKU GatedVaractorTuningCurve 0123456...
