"The Linvill transistor model may be used for transistor synthesis if the model accurately approximates transistor response and may be readily simulated on an analog computer. Experiments were performed on a transistor to determine the Linvill model parameters. The transistor's large-signal transient response was investigated by pulsing the emitter with a current that drove the transistor from the active region of operation into saturation. The same problem solved experimentally was then solved analytically by replacing the transistor with the Linvill model. The experiment was then simulated on an analog computer by using the equations that govern the Linvill model's response.
A comparison was made between the experimental solution and the analytical solution to determine how well the Linvill model approximated transistor response. The comparison revealed that the model approximated transistor response very well over most of the range of operation. However, it was shown that the collector capacitance could not be neglected if the model was to approximate transistor response over the entire range of operation. The analytical solution and the analog solution were compared to determine how readily the Linvill model could be simulated on an analog computer. The comparison indicated that the Linvill model could be simulated very easily and accurately on an analog computer.
Suggestions were made on how to account for collector capacitance in the model. It was also pointed out how the modified model could be simulated and thereby used for transistor synthesis"--Abstract, pages ii-iii.
