I hope you haven't implemented the ngspice brain damage that causes it 
to apply the m= multiplier repeatedly for each successive "analysis" 
(your transistors grow as you proceed).

I think I'd be using gnucap if it could do noise analysis. But I have a 
hacked up ngspice/spicepp combination that works with TSMC parameter 
sets, making it hard to change for just part of job.
