Here, a new analytical method, state matrix transform method, is proposed for calculating the descriptions of current waveforms generated by commercial electrostatic discharge (ESD) generators. This method can be used to analyse and design lumped parameter ESD circuits. A relatively simple eight elements ESD circuit model is established and used to predict the current waveform of human-metal ESD events. To calibrate the ESD simulator, a mathematical expression of four exponentials curve for ESD current waveform is given. This careful theoretical study of ESD current waveform calculation makes an innovative contribution to ESD generator circuit simulation and design, and it provides a new mathematical description for ESD sensitivity test.
Abstract. The method of locating air flight targets and measuring the speed of air flight targets by the passive electrostatic detectors is studied, and we derive the mathematical expression of the induced current at the detection electrode. The simulation of the change of the induced current with the horizontal distance is carried out, and the simulation results verify the feasibility of detecting the target by detecting the current. Finally, the relationship between the horizontal detection distance and the area of the detection electrode is simulated.
