Common-mode rejection

Depending on the application for the ECG subsystem, there are clinical situations where the CMR (common-mode rejection) must be very high. The AAMI (Association for the Advancement of Medical ...

Understanding Common-Mode Differential Pressure

When pressure sensors are used to measure differential pressure (ΔP) for sensing flow, the common-mode pressure issues need to be considered. This is especially true for applications such as medical ...

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 ...

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 ...

About Common-Mode Rejection

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 ...
