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 ...

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 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 ...

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 ...

The problem with tube based audio is that it has so often been hijacked by people for whom the bragging rights of having a ...

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, ...

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 ...

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 ...

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 ...
