Re: I added a CD4007 model

Hello, The model DC characteristic may be ok, but? model with no capacitances is not reasonable.? You might be better off using LTspice logic devices. Rick

Hi all,
I was missing a CD4007 model, so there it is.
It is bare bones hierarchical model (so far) that I left that way so that it is easier to check what I did. If everything goes well, I'll make a subcircuit out of it.
The transistors models are based on the 4007 library used at csupomona.edu, like this:
.model NMOS NMOS LEVEL=2 VTo=1.4 Kp=.6m LAMBDA=0.005
.model PMOS PMOS LEVEL=2 VTo=-1.0 KP=.6m LAMBDA=0.01
No diodes or capacitances, and no resistors in this model. Just MOSFETs. Surprisingly this simple model produces a very nice Rds_on transfer plot, and triggers no alarms in error log.
So far I'm happy with it.
In CD4007L2_h.asc which is a hierarchy file i placed some comments about an easy way procedure of making a symbol out of a hierarchy, but
please don't consider it a tutorial of any kind.
