We’ve covered the Tiny Tapeout project a few times on these pages, and while getting your digital IC design out there onto actual silicon for a low cost is super cool, it is still somewhat limited. Now, along comes the German FMD QNC project funding MPW (multi-project wafer) runs not in bog standard Silicon CMOS but Silicon-Germanium bipolar technology. And this is accessible to you and me, of course, provided you have the skills to design in this high-speed analog technology.
