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 ...

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 ...

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 ...

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 ...

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, ...

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 ...
