Dynamic latchup study using transmission line pulses and picosecond imaging circuit analysis [CMOS IC latchup]

In this work, we present a methodology based on the combination of transmission line pulse (TLP) stimulation and picosecond imaging circuit analysis (PICA) for studying the dynamic onset of latchup. A mathematical model, based on carrier recombination equations, is also discussed and is shown to be in very good agreement with experimental data.
