Neurospace Mapping Modeling for Packaged Transistors

Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018
This paper presents a novel Neurospace Mapping (Neuro‐SM) method for packaged transistor modeling. A new structure consisting of the input package module, the nonlinear module, the output package module, and the S‐Matrix calculation module is proposed for the first time. The proposed method can develop the model only using the terminal signals, instead

Analysis of Kirk effect of an innovated high side Side-Isolated N-LDMOS device

MATEC Web of Conferences, 2016
An ESOA of LDMOS device is very critical for power device performance. Kirk effect is the one of the major problem which leads to poor ESOA performance. The cause of the problem mainly due to the high beta value of parasitic NPN transistor in the p-body.

Automatic optimal design of field plate for silicon on insulator lateral double‐diffused metal oxide semiconductor using simulated annealing algorithm

IET Power Electronics, Volume 17, Issue 4, Page 487-493, 18 March 2024.
In this paper, an automatic optimal design method for field plate (FP) in silicon on insulator lateral double‐diffused metal oxide semiconductor using simulated annealing algorithm is proposed. For a given device structure, the framework can automatically design the FP geometry parameters within the definite range that maximizes the device breakdown ...
