In order to provide electrostatic discharge current in study of electrostatic discharge, several common used methods of representing electrostatic discharge current are analyzed. Method of computing electrostatic discharge current by use of electric circuit model is emphatically discussed . Four electric circuit models are presented. Solving differential equation method and complex frequency domain method to deduce analytical expression of electrostatic discharge current are discussed. Current curves are calculated and plotted using given circuit parameters. Comparison of these electrostatic discharge currents shows that these circuit models have their own features in current waveforms. Current of six element model has two-peak waveform. Current of nine element model has further current oscillation feature. Thus, electric circuit model should be selected according to concerned items in study of electrostatic discharge.
