SPICE Models

SPICE models for all of the transistors used in the LTspice simulations in the book are available here. I have found that manufacturers' models are often quite inaccurate, so I created the models here for use in the book simulations. These models have been adjusted for better conformance with datasheet information and, for transistors, for conformance with actual DC measurements of samples of the real devices.

The small-signal BJT transistor models were updated in April, 2011 to include better estimates of base resistance (RB) to improve the accuracy of noise simulations.

The single file contains models for BJTs, JFETs, power MOSFETs, diodes, rectifiers, Zener diodes and LEDs. Most of the device part number designations end with the letter C to designate them as Cordell models so that they will not be confused with other manufacturers' models that may be in the LTspice library. All of the supplied book simulations use these parts, and the Cordell Models file is incorporated into the simulation files with a .include statement.

The power MOSFET models in this file are in the LTspice VDMOS format.
