Hicum model manual

A scalable SPICE model is available for this family of bipolar transistors (lines in Fig. 5) using the state-of-the-art HICUM/Level2 compact model [9]. Custom spiral inductors, transmission lines.  · model modelname HICUM [parm=value]* The model statement starts with the required keyword model. It is followed by the modelname that will be used by transistor components to refer to the model. The third parameter indicates the type of model; for this model it is HICUM. Use either parameter NPN=yes or PNP=yes to set the transistor type. Model features overview HICUM is a semi-physical compact bipolar transistor model. Semi-physical means that for arbi-trary transistor configurations, defined by emitter size as well as number and location of base, emit-ter and collector fingers (or contacts, respectively), a complete set of .

In order to customize the HICUM model for a given transistor fabricated in specific technology, one has to extract the parameters associated with each model equation. Except for a few parameters responsible for the accurate prediction of high-frequency behavior of SiGe HBTs, HICUM extraction strategies are well documented and reported in the. HSPICE® Elements and Device Models Manual Version X, September HiCUM is an advanced transistor model for bipolar transistors, with a primary emphasis on circuit design for high-speed/high-frequency applications. HiCUM development was spurred by the SPICE Gummel-Poon model's (SGPM) inadequate level of accuracy for high-speed large-signal transient applications and the required high-collector current densities.
