The 2024 editions of Quad’s iconic 33 pre-amplifier and 303 stereo power amplifier have landed in Berlin for review. Here are 20 more thoughts on their designs: 1. Released in the late 1960s, the ...

Abstract: We present a compendium of generalized expressions for the low-frequency voltage gain and terminal impedances of each of the three fundamental bipolar-amplifier topologies (i.e., common ...

A new study shows that electronic chips can be dramatically simplified by using the “edge of chaos,” which enables long metal lines to amplify signals and act like superconductors, reducing the need ...

Communication satellites and flying antenna platforms can contribute to the comprehensive and resilient operation of global mobile networks of the fifth and sixth generation (5G, 6G). However, as ...

When most people think of tube circuits, the first thing that comes to mind is often the use of high-voltage power supplies. It wasn’t a given for tube circuits, though, as a range of low-voltage ...

There are few inventions that have been as crucial to the evolution of pop and rock music as the guitar amplifier. Indeed, many cite the 1951 Sun Records recording session of Jackie Brenston and his ...

What are Gallium Nitride Semiconductors? Semiconductors play a critical role in wireless networks as they are used to manufacture the components that make up these networks like radio frequency ...

Prior to Bell Labs’ first working transistor in 1947, which ushered in the advent of semiconductor technology and the computer age, every long-distance telephone call, radio and television broadcast, ...
