Common-mode rejection is the ability of the differential amplifier (which sits between the oscilloscope and probes as a signal-conditioning preamp) to eliminate the common-mode voltage from the output ...

Process control and data acquisition systems often make differential measurements so that they can isolate the desired differential signal from unwanted common-mode signals. For example, when ...

It's no longer sufficient to just perform static CMR tests on isolators. You have to look at the dynamic performance of optical, magnetic, capacitive, and RF implementations. Static common-mode ...

Differential amplifier circuits, such as the one illustrated in Figure 1, are required in analogue technology for a wide variety of applications. One example is measurement technology in which, ...

Circuit designers often encounter the adverse effects of common mode noise on a design. Once a common-mode problem is identified, there are several ways that it can be resolved. However, common-mode ...

Differential signal transmission is widely employed in modern electronic systems to maintain signal integrity and high data rates while minimising interference. However, common-mode noise—undesirable ...

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 ...

Nexperia has announced the PCMFxUSB3BA, a common mode filter (choke)/ ESD protection combination. The filter features a differential passband of up to 10GHz 3dB frequency and surge robustness up to ...

Murata has unveiled the wire-wound common mode choke coil (CMCC) DLW32SH101XF2, which it says is the world’s first CMCC to support the most challenging requirements of differential to common mode ...

NXP Semiconductors today announced the availability of a new family of Common Mode Filters (CMF) with integrated ESD protection for high-speed MIPI D-PHY and HDMI interfaces. Offering industry-leading ...
