You've got H&H, right? study sections 2.03 and 2.04. (I personally don't like the way H&H approaches the various transistor models. But that may be due to having learned it a different way/order via Sedra & Smith. YMMV - everyone has a learning methodology that works best for themselves) -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
