In a world of tight timelines and ever-increasing performance requirements, it’s critical to create circuit designs right the first time; thus, engineers in the analog and mixed-signal industry often ...

We analog designers take great pains to make our amplifiers stable when we design them, but there are many situations that cause them to oscillate in the real world. Various types of loads can make ...

This article started because a good friend of mine dropped a Panasonic SA-XR50 switch-mode amplifier to me for some basic bench test. This article will NOT be a review of that unit, but an ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

It seems apparent these days that home theater has pushed beyond the boundaries of “excessive” as evident by the almost endless options of surround processing, video formats, and the number of ...

Depends on the amp's slew rate too. If the amp is feeding a high impedance then it is pushing more volts and less amps for the same wattage. If the amp cannot slew fast enough, it'll distort. This ...

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 ...
