Abstract |
The ESD protection characteristic of chip varistors on a circuit board can not be analyzed by using a conventional circuit simulator due to its microwave characteristic. Thus, by employing Agilent's microwave circuit simulator ADS, we showed that the ESD Protection characteristic or chip varistors can be investigated. order to got more precise simulation results, a chip varistor model was extracted from the electrical characteristic of a TDK's chip varistor and the distributed circuit based pattern was designed as the ESD propagation path. The simulation results showed that the ESD protection characteristic of a chip varistors can be improved drastically by reducing the ESD propagation path. |
