CD4007 Specs: Vtn, kn, Channel Length Modulation

[KeithLucas]

I'm looking for the threshold voltage Vtn, the MOSFET transconductance parameter kn and the channel length modulation parameter for MOSFET 6 on the CD4007. Where can I look these values up?

 

[davenn]

did you try the datasheet ?
would be the obvious starting place

Did YOU try the data sheet? Not such an obvious place for what was being asked.

Moving on:

OP, Which FET do you consider to be #6?

The answer would be foundry and process dependent and I doubt it is available on any data sheet. Maybe you can look for a spice model and either read the model (if it is readable), or use spice to extract the data.

Here is a lab example

EDIT

Here is the spice model

Thanks, I'll run a SPICE model to get it!
