Abstract :
A distributed-circuit model is presented that analyzes the transient response and radiation rate threshold of a MOSFET under ionizing radiation. A system of ordinary differential equations with variable coefficients that govern the lateral base voltage distribution and the transient response of the parasitic bipolar transistor is developed and numerically solved. The BAMBI device simulator is used to calculate the I-V characteristics of the individual bipolar transistors used in the model under high injection situations
