LDMOSFET for Smart Power IC Design


Model Description This lumped-charge LDMOS model provides a physically-based compact model for LDMOS IC design. It is designed to replace other models (like the modified BSIM3) not specifically designed for the LDMOS structure. The model includes moderate inversion and effects of high field on carrier mobility.
Model Parameters The model contains 38 parameters. Please see the model source code for the list of parameters. 
Performance Level: ACCURATE
Quality Classification: 2B
This model has been extensively used. 

As in most compact models for IC design, parameter extraction is based on process and structure information
