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 ...

The ACPL-x6xL products are optically coupled ultra-low power 10 MBd digital CMOS opto couplers that operate with low power consumption, especially when the light emitting diode (LED) operates at low ...

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 ...

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 ...

When you must measure a differential signal, perhaps from a thermocouple or bridge, the two signal wires will also pick up some unwanted signals. In a lab environment, those signals may appear ...

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, ...

Abstract: This research extends the idea of common mode rejection in a single DC-link fed emulator and drive inverter setup using a transformer. The study proposes a systematic method to design the PI ...

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 ...

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 ...

The DIA2240 device is an automotive qualified high precision, bidirectional and zero-drift current sense amplifier with enhance PWN rejection. The device sense drops across the shunt resistor over a ...
