The differential outputs provided by fully differential amplifiers (FDA) can be used in a positive feedback scheme to generate a partially active output impedance. Applying this technique, to set the ...

It’s common practice to series-terminatean op amp to match theimpedance of the load. This practicecauses a 3-dB loss of output power in thetermination resistance, however (Figure1). Newer op amps ...

Members can download the PDF ebook. A few engineers were having a debate. According to all the books, some of them said, op amps are supposed to have zero output impedance, or very low. That means the ...

In most power-supply design examples it is common to arbitrarily place the crossover frequency at one-fifth or one-tenth the switching frequency. However, the crossover frequency actually affects the ...

Does anyone know the output impedance of the USB VBUS connector? I ran a quick search through the USB 2.0 spec and couldn't find any values. A quick google pulled up some fairchild docs for a ...

This “Product How-To” article focuses how to use a certain product in an embedded system and is written by a company representative. Audio amplifier products are becoming more and more advanced in ...

Our recent contribution to the Workbench column in Radio World about our home-brew construction of an XLR-3 cable tester produced a notable, positive reader reaction. It seems almost all of us in the ...
