Re: [EE]:: Free book - Designing Analog Chips

I had never heard of Tiny Tapeout. Thanks for that. There used to be a
service call MOSIS which provided relatively inexpensive access to
fabrication (think about $1k US for a simple analog IC). It looks like they
still have a version of it called MOSIS 2.0 - I don't know what has changed
about it.
