What do you need our team of experts to assist you with? Bottom junction built-in potential Coeff. SPICE models range from the simplest one line descriptions of a passive component such as a resistor, to extremely complex sub-circuits that can be hundreds of lines long. Bulk charge effect coeff. For the voltage controlled switch, nodes nc+ and nc- are the positive and negative controlling nodes respectively. 0 EF - Source/drain side junction capacitance per unit length 0 - prev["dsbl"] = "wwhgifs/prevdsbl.gif"; Value is the voltage gain. DWC - As we have seen previously, we can easily change the parameters of these “bare-bones” models so that our circuits Mname is the model name, Area is the area factor, and OFF indicates an (optional) starting condition on the device for dc analysis. n+ is the positive node, and n- is the negative node. Parameter V/m A fallback strategy is to build a SPICE model from those parameters listed on the data sheet. Description Simplifications are made to speed simulation time, and various performance parameters are adjusted to match the model to measured device performance. Body-effect of mobility degradation 0.53 If you’re building models for specialized components, you need to define model parameters from your component datasheets. Gate-drain overlap capacitance per unit W Embedded Control and Monitoring Software Suite. MOBMOD Value is the resistance (in ohms) and may be positive or negative but not zero. 1.0 0 2.2 ALPHA0 nS is the (optional) substrate node. NOIC By simulating your circuits, you can detect errors early in the process, and avoid costly and time consuming prototype reworking. The (optional) initial condition is the initial (time-zero) value of inductor current (in Amps) that flows from n+, through the inductor, to n-. 1.0 Channel width reduction on one side V/K 3 -0.07 CGDL PDIBLC1 of length dependence for width offset Interface trap density One and only one of these parameters must be given. Next modify the model definition so that model parameter Vto value is read from above PARAM part property Vto. 0.56 First non saturation factor Power of length dependence for length offset RBSB 0.1 2.4E-4 Description Light doped drain-gate region overlap capacitance PBSW Constant term for the short channel model From LTwiki-Wiki for LTspice.
