The implementation is standard Berkeley but with the addition of the 'M' instance parameter which specifies the number of equivalent parallel devices.
Original Berkeley documentation is provided on the CDROM and at our web site. Please visit Further Documentation for details. Note the document covers version 4.70 of the model. Earlier versions are available from the BSIM3/4 web site at BSIM Reference.
BSIM4 devices may be binned according to length and width. Refer to Model Binning for details. Note the multi-fingered devices are binned according to width per finger.
