We recently took a long look at electromagnetic interference (EMI) and how to combat this type of noise. The solution—the so-called instrumentation amplifier—is yet to come. But before we can get ...

Static common-mode specifications have been the traditional standard used to measure isolators and compare devices with different construction or technologies. However, that standard is no longer an ...

When you must measure a differential signal, perhaps from a thermocouple or bridge, the two signal wires will also pick up some unwanted signals. In a lab environment, those signals may appear ...

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 ...
