Hi Wimberlytech and the group,
I have modelled lots of circuits in LTspice, but never tried IC design. I know that this can be done, I have heard that Linear Tech used LTspice for many of their IC designs.
I followed instruction that I found here:
http://www.blog-tm.de/?p=291And inserted the PTM from here:
http://ptm.asu.edu/modelcard/2006/65nm_bulk.pmI assume that this is the NMOS and PMOS models for 65nm process.
I used the W parameter to vary the geometry between the MOSFETs and built a 1:12 current mirror:

This gives M2 drain current is 1.2mA (not the desired result)
Do I have set other parameters?
I assume that you need a PTM for the process that you are using?
The LTspice License agreement includes:
4. Restrictions. Licensee shall not ...
Snip ..
This program is specifically not licensed for use by semiconductor manufacturers in the design, promotion, demonstration, development, or sale of their products. Specific permission must be obtained from Analog Devices for the use of LTspice for these applications.
I guess it is okay for educational use.
