Use any PSIPCE software, it would be nice if you could use the same transistor models as them, but any high level CMOS model should give pretty decent results.
Just insert a current source where Ib1 is shown (you could implement one, but I would stick with an ideal one to begin with.)
I would imagine it will take quite a bit off fiddling to get that to work as shown.
I use Cadence with the 0.35um AMS process, I'm quite sure they use the BSIM 3 model. One of my colleagues uses winspice with the BSIM models. Pretty much any SPICE simulator will run the BSIM models.
Several months back I had a check on what models Orcad was was using, and the BSIM ones were there somewhere, I can't remember what they were called, level 7 or level 9 I think.
Spending 15 minutes on google should be able to clear this up.
If I was you I would pick the simulator you like best, then find out which 'level' is the BSIM model.
