Over the years one sees (and occasionally uses) all sorts of strange  
permutations. One of my favorites is the op amp with its "output"  
grounded and its "power" pins used as differential current outputs!

And here I am, replying to you, and getting my fingers into  
spicepp.pl (I need some small changes to get it to translate TSMC  
models for ngspice), and there's *your* name at the top. Thank you  
very much!
