In this episode, we design a simple D/A converter, correcting some of the faults of the direct converter that we saw in episode 2. We examine several things that can go wrong with it, especially resistor mismatch and clock skew.
All the circuits demonstrated are from previous episodes. Schematics are on the project GitHub, https://github.com/kennykb/kevins-cav... and https://github.com/kennykb/kevins-cav...
