The selection of component values for common mode filters need not be a difficult and confusing process. The use of standard filter alignments can be utilized to achieve a relatively simple and ...

In many industrial applications, signals requiring analog-to-digital conversion ride on a large I common-mode signal of up to a few hundred volts. A familiar problem ...

Fully differential amplifiers have grown in popularity because of their low distortion, excellent noise rejection, and the simplicity of interfacing them with differential analog-to-digital converters ...

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 ...

External noise sources inject signals into analog-input circuits at every opportunity. Good grounding practice, prudent use of shields, decoupling capacitors, separate analog and digital grounds, ...
