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 ...

These three analysis methods are linked together, so this section is organized by control method. In contrast to the large-signal transient response that was reviewed in part 2, we will perform ac ...

As you can see, there are a number of variables and the answer is simply not that straight forward. When conducting amplifier measurements, we tend to be a bit more forgiving with receivers than multi ...

As you probably know if you've been shopping for cables, coax for most video applications is "75 ohm" coax–but what the heck does that mean, anyway? This article is a short, non-technical explanation ...
