Great new video by Dave talking about the impacts of value, type and placement of bypass capacitors in digital circuits. Have any of you had issues figuring out bypass caps?
I definitely have. I build a flight control board for a mini drone and had a ton of issues with the right value of bypass caps for the micro. the large inductive load had so much of an effect on the battery supply rail even with fly-back diodes that it was causing the micro to reset. I finally got two separate caps that were of different values a 10n multilayer ceramic and a 4.7U multilayer ceramic to get the micro’s power rail to smooth out.
Great video! Especially for someone like me who is more of a visual learner. The most fascinating part for me was where he whipped out the spectrum analyzer and measured the EMI being generated by the loop area. This was a great followup video from his Muntzing one he published a couple weeks back.
