Four Order ESD Generator Circuit Model and its Simulation

Basis international electrician committee issued IEC61000-4-2 testing standards, proposed a new ESD current expression. Using Laplasse transform, established the ESD system mathematical model, according to the mathematical model, construction of passive four order ESD system circuit model and active four order ESD system circuit model, and simulation. The simulation results meet the IEC61000-4-2 standard, and verify the ESD current expression, the mathematical model and the circuit model of consistency.
