Many factors increase the amount of “noise” interference that can damage or disturb the functionality of electronic devices. Today’s automobiles are a prime example. In a single vehicle, you can find ...

A common mode inductor, also widely known as a common mode choke, is a specialized four-terminal coupled inductor designed to eliminate common-mode electromagnetic interference while leaving useful ...

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 ...

Sumida launches DC common-mode chokes up to 16 A for automotive power electronics, reducing EMI in traction inverters and onboard chargers.

In our quest to describe the instrumentation amplifier, we began by exploring electromagnetic interference (EMI) and what to do about it. We then examined the basis of instrumentation amplifiers, ...

The identification and elimination of noise has always been a major concern in the installation, testing, and certification of LAN networks, as well as a key part of ongoing network maintenance and ...

In DC to low-frequency sensor signal-conditioning applications, relying on the common-mode rejection ratio (CMRR) of an instrumentation amplifier to provide robust noise rejection in harsh industrial ...

According to IEEE/ANSI Standard C62.41-1991 (formerly IEEE Standard 587), Recommended Practice on Surge Voltages in Low-Voltage AC Power Circuits, the worst normal mode surge expected inside a ...

An isolated probing system, the R&S RT-ZISO measures fast switching signals in environments with high common-mode voltages and currents. Its power-over-fiber architecture galvanically isolates the DUT ...

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 ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...
