To understand how common-mode signals are created and then suppressed, you should first understand the interaction of shields and grounds in common cable configurations. The following discussion ...

When working with real-world signals, designers often face the significant challenge of picking out a small signal from a large and varying common mode voltage. An ideal op amp would reject the common ...

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 ...

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 ...

Modern measurement systems often operate with single 5-V power supplies, yet their input signals may have large common-mode voltages that exceed the supply by tens or hundreds of volts. Also, unless ...

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 ...

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 ...
