Default Value(NMOS/PMOS) SPICE model The SPICE model of a bipolar transistor includes a variety of parasitic circuit elements and some process related parameters in addition to the elements previously discussed in this chapter. 1 RBPS First substrate current body-effect coefficient SPICE Model Parameters The model parameters of the BSIM3v3 model can be divided into … Threshold Voltage Noise parameter C 2.5E-6 If you do not find the SPICE Model you need, please click on the "Spice Model Request" button below and fill in ALL the fields. Since the user of the former model revision, BSIM4.2.2, is used to the already implemented parameters, the new parameters are added on top of the parameter list for BSIM4. 5E4 / 2.4E3 PDIBLC2 Parameter Parameter for smoothness of effective Vds calculation 0 If the temperature of the device is raised to 75 ° C, what is the new I CBO? 0 Commercial and industrial SPICE simulators have added many other device models as technology advanced and earlier models became inadequate. Body effect coefficient of output resistance DIBL effect CDSC 0, Table 35 Temperature Modeling Parameters gamma2 VSAT L and W are the channel length and width, in meters. ACNQSMOD Junction current temperature exponent coefficient First coefficient of short-channel effect on VTH Embedded Control and Monitoring Software Suite. Mobility n+ and n- are the positive and negative nodes, respectively. First coefficient of narrow-channel effect on VTH Second coefficient of short-channel effect on VTH F/m2 1 DIBL coefficient in the subthreshold region Emission coefficient of junction Cname n1 n2 . One and only one of these parameters must be given. UC Bulk charge effect width offset Spice Models Request Form. Doping concentration near interface Gate dependence of Early voltage For BiCMOS devices, use the high current Beta degradation parameters, IKF and IKR, to modify high injection effects.
