Ex-movie theater projectionist Steve Guttenberg has also worked as a high-end audio salesman, and as a record producer. Steve reviewed audio products for CNET and worked as a freelance writer for ...

Power amplifiers (PAs) are pivotal elements in modern wireless communication and radar systems, where enhancing output power and efficiency remains a critical challenge. Recent advances in PA design ...

The x1 voltage amplifier or “buffer” is a standard building block of analog design. This article presents the design of a discrete, low-parts-count, high-performance, matched-transistor buffer, and ...

CMOS amplifier design remains a critical focus in modern electronic research, particularly with the growing demand for low power consumption and high performance in integrated circuits. Central to ...

We uncovered an audio myth on our YouTube channel I didn’t even know was being perpetuated by some esoteric amplifier companies. Apparently there is a belief that designing an amplifier to be too ...

The literature on power amplifiers frequently discusses the importance of power-supply rejection in audio amplifiers, particularly in reference to its possible effects on distortion [4]! I have (I ...

After 40 years of creating audio equipment, the last thing that Kostas Metaxas wanted to produce was “another box with transistors on a heatsink”. He was dreaming of the most spectacular architecture, ...

A design for a new broad-bandwidth amplifier for detecting single microwave photons has been unveiled by physicists at the University of California, Berkeley and the Lawrence Berkeley National ...

Members can download the PDF ebook. After I wrote up that amplifier scheme (see “What’s All This Bridge Amplifier Stuff, Anyhow?”), I was thinking about how to get better common-mode (CM) range. That ...

Meters, toggles and switchable between Class A/B and Class A operation – could this be an enthusiast's dream?

The designs and innovations created by these much-sought-after gurus have shaped the amps of today, and continue to shape the ...

Everyone has a chip-of-shame: it’s the part that you know is suboptimal but you keep using it anyway because it just works well enough. Maybe it’s not what you would put into a design that you’re ...
