Learning Analog System Design With the MOSbius: A Chip that will Teach you the Real-World Ropes

When it comes to learning digital system design, hob-byists and students have a lot of options, whether it's tinkering with field-programmable gate arrays or working up a chip submission for a Tiny Tapeout run. But similar tools for analog design have been harder to come by. Certainly you can create analog circuits in a simulator like LTspice and test them against theory. But nothing beats building real analog circuits and measuring their actual, not theoretical, behavior. Measurement is complicated for analog designs because the test equipment can affect the very measurement being made.
