The development of digital common-mode noise starts with digital circuit devices. Peak overshoot and undershoot currents from the devices conduct into the power and return planes to result in this ...

This post is sponsored by Texas Instruments. The INA300 is a high common-mode, current-sensing comparator that is configured to detect overcurrent conditions through measuring the voltage developed ...

If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...

Using a resistor and voltage amplifier across it for current sensing presents a conundrum. On one hand, it appears to be near-trivial application of Ohm’s Law via I = V/R. It certainly looks easy: A ...
