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 ...

If you ever wanted to build your own tube amplifier but you were intimidated by working with high voltages, [Marcel]’s low-voltage tube amp design might spark your interest. The design operates with a ...

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 ...

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 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 ...

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 ...

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, ...

It is essential to use a combination of specialized and general CAD tools in RF and microwave solid-state power amplifier design. June 17th, 2020 - By: Wolfspeed, a Cree Company In the world of RF and ...

Originally, operational amplifiers (op amps) were not thought of as candidates for RF design, but the advent of newer, faster devices has now made them an attractive option for some applications. The ...

Sometimes I wish FETs had become practical before bipolar transistors. A FET is a lot more like a tube and amplifies voltages. Bipolar transistors amplify current and that makes them a bit harder to ...

Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...

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 ...
