Results are presented on generalized approaches to derive radiation-inclusive simplified models of linear and digital microcircuits. Application of the principle of superposition allows generation of a compact small-signal model of the linear microcircuit, with extension of the model to include large-signal saturation effects. The digital microcircuit model is the combination of current-voltage terminal networks with a logical decision function to represent the truth table of the device. A factor of 20 to 50 improvement in required computer time and storage was realized with the terminal models over detailed models, with no significant loss in the representation of key performance parameters or radiation vulnerability. The linear modeling technique suggests that photocompensation networks can be applied successfully at the terminals of the device.
