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. When I present seminars, I often ask the members of the audience to hold up their hands if they think bipolar op amps have better gain and linearity than CMOS. I ...

Much ballyhoo surrounds the concept of "damping factor." It's been suggested that it accounts for the alleged "dramatic differences" in sound between tube and solid state amplifiers. The claim is made ...

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 ...

What are the risks when driving a 4 or 6 ohm speaker with a amplifier that is rated from 8-16ohm. The amplifier is an old Pioneer VSX-808, it´s my "PC speakers" and I´m using 4 ohm speakers as front ...

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 ...
