Level 8 MOSFET models for the PMOS and NMOS FETs in the CD4007 mosfet array chip courtesy of Dr Lynn Fuller of R.I.T.
- LTSpice Schematic file – All the model parameters are included as spice directives on the schematic so this should be portable and run right out of the box on your machine.
- Plot Specification file – goes with the schematic file and plots the I-V characteristic of the PMOS FET and gm/Id which allows the specific current to be calculated
