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 ...
Engineers often perceive RF-low-noise-amplifier design as a difficult task. Obtaining a low-noise figure with high stable gain can be challenging—even intimidating. However, with the recent evolution ...
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 ...
In the intervening 21 years between completing his further education (1990) and starting at Naim (2001), Sells earned his ...
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 ...
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 ...
Cell phones have come a long way in terms of battery life, but lets be honest, there's still plenty of room for improvement. The very fact that we talk about using a phone for eight hours as being ...
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 ...
