mosfet.tex is by Ramón Jaramillo, found at www.texample.net and it is
not in the PGF/TikZ manual so it is under the CC-BY license. [ see
http://www.texample.net/tikz/examples/about/ ]

The remaining files are licensed under the MIT License : there is
doubt about how examples taken from stackexchange.com are intended
to be licensed, see
http://meta.stackexchange.com/questions/54766/code-at-stackoverflow-under-any-license
because the CC-BY-SA license is not intended for software.
I consider that using the examples in this way amounts to fair use.
