Abstract
A new circuit for producing simulated electrostatic discharges (ESD) based on the Human Body Model (HBM) is disclosed for testing integrated circuits. HBM ESD test systems provide stress pulses defined by industry standards. The pulses produced by prior art have small imperfections or anomalies. These anomalies can cause incorrect testing to certain devices. The improved ESD HBM test system herein disclosed provides pulses meeting the requirements of industry standards while reducing several anomalies to negligible levels.
