Abstract
The present invention relates to a method which introduce a parasitic series resistance for solving electrostatic discharge voltages by using transmission line pulse method and least square error solution method. In present invention, we introduce a parasitic series resistance, Rs, into the equation which presents the correlation between the transmission line pulse method and human body model. The equation is then rewritten aselectrostatic discharge voltage=electrostatic discharge current×(the human body equivalent resistance+the parasitic series resistance) We can obtain the optimal parasitic series resistance and electrostatic discharge voltage by using the least square error solution method. By making a comparison between the electrostatic discharge voltage obtained from transmission line pulse method and that obtained from human body model test method, we can find that the correlation of the transmission line pulse method and human body model in this invention is better than that in conventional method.
