Let's see how we could build a differential probe for our oscilloscopes, one that is really cheap (around 20 $) and that goes up to 1 MHz, which is good enough for DC projects, AC power circuits, AF circuits and even SMPS.
00:00 - introduction, motivation of the project
07:20 - features and design presentation
18:20 - why 26V power voltage ?
27:00 - creating the virtual ground
30:00 - the input voltage divider
36:40 - the input protection diodes
41:20 - details regarding the instrumentation amplifier
45:50 - input offset voltage compensation
48:20 - the frequency compensation
1:02:30 - how to do the adjustments
1:07:55 - performance showcase
1:23:00 - the PCB layout
