| Outline of Final Research Achievements |
ESD protection devices are frequently used on electronic circuits to protect electronics from electrostatic discharge. In this research, we improved our previous proposed methods on detail measurement of ESD protection devices’ characteristics and dynamic characteristic modeling of ESD protection devices for radio-frequency circuit simulations used in the electronic circuit design.
Furthermore, we investigated how to apply the measurement method to varistors, a kind of protection device. Although application to varistors measurement was still under development, the method could measure slight differences in the characteristics among multiple types of varistors with the same specifications. Therefore, it showed that the method could establish in the near future.
