Use Dynamic Common-Mode Rejection Test To Evaluate Industrial Isolator Performance

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 ...

Common-Mode Filter for Automotive Ethernet Claims Lowest Parasitic Capacitance

The newest member of TDK’s lineup of common-mode filters for 10BASE-T1S automotive Ethernet systems, designated ACT1210E-131-2P-TL00, lowers the line-to-line capacitance by approximately 30% based on ...

Common-Mode Noise Suppression in Differential Signal Transmission

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 ...

Isolated probe limits common-mode noise

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 ...

Eliminate crossover distortion in rail-to-rail amplifier design

All operational amplifier (op-amp) datasheets have an input voltage range limitation called the common-mode range. Strictly speaking, the common-mode voltage is the average voltage on the two inputs ...

Current Mirrors Tame Common Mode Noise

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 ...
