| 4 | spice \- electronic circuit simulation program | |
| 5 | .SH SYNOPSIS | |
| 6 | .B spice | |
| 7 | .SH DESCRIPTION | |
| 8 | .I Spice | |
| 9 | is a general-purpose circuit simulation program for nonlinear dc, | |
| 10 | nonlinear transient, and linear ac analyses. Circuits may contain resistors, | |
| 11 | capacitors, inductors, mutual inductors, independent voltage and current | |
| 12 | sources, four types of dependent sources, transmission lines, and the four most | |
| 13 | common semiconductor devices: diodes, bjts, jfets, and mosfets. | |
| 14 | .PP | |
| 15 | Spice has built-in models for the semiconductor devices, and the user need | |
| 16 | specify only the pertinent model parameter values. The model for the bjt is | |
| 17 | based on the integral charge model of Gummel and Poon; | |
| 18 | however, if the Gummel-Poon | |
| 19 | parameters are not specified, the model reduces to the simpler Ebers-Moll | |
| 20 | model. In either case, charge storage effects, ohmic resistances, and a | |
| 21 | current-dependent output conductance may be included. The diode model can be | |
| 22 | used for either junction diodes or schottky barrier diodes. The jfet model is | |
| 23 | based on the fet model of Shichman and Hodges. The model for the mosfet is | |
| 24 | based on the Frohman-Grove model; however, channel-length modulation, | |
| 25 | subthreshold conduction, and some short-channel effects are included. | |
| 26 | .PP | |
| 27 | Spice reads a circuit description of the form described in the Spice users | |
| 28 | guide and produces line-printer output. The character plot width may be | |
| 29 | altered to suit the output device (see .WIDTH option). | |
