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 ...

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 ...

It is well known that combining a transformer with various types of amplifiers can improve the dynamic range. This works particularly well driving into the inverting side of either a differential dual ...

The operational amplifier is arguably the most useful single device in analog electronic circuitry. When you apply them in the circuits, you must know their basics and functions. As for the function ...
