An Inductive Method for ESD Current Capture on the ESD Generator Tip Using Two-Step Analog Integration

The paper presents a lightweight current capture device for electrostatic discharge (ESD) testing. The device contains a magnetic field sensor, which is mounted on the tip of the ESD generator. A two-step analog integration is performed to correct the frequency response of the sensor from 1 MHz to 800 MHz, thus ensuring the reliable capture of ESD current. The ESD current waveform is different for different test scenarios. The proposed device can measure the waveform for each discharge scenario. The measured results in the frequency and time domains are presented in the paper.
