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 ...

For the PDF version of this article, click here. Designing a high-speed, high-current amplifier able to deliver at least 50 V RMS is no simple task. For whatever the amplifier will be driving — a ...

A new amplifier had to be developed to replace an existing amplifier which had been a sound product for many years, but the RF bipolar power transistors used in it had become obsolete. This ...

One of my first jobs as an engineer was at Empire Scientific Corp. in Garden City, NY in 1972. This was a high-end audio company that made speakers, turntables and phonograph cartridges. We had some ...

Learn how power amplifiers work, the common types, and what to lookout for when shopping for amps. You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before ...

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 ...

The switching amplifier, or class D amplifier, has risen quickly to prominence in consumer audio applications, from MP3 devices including mobile phone handsets to games consoles, LCD-TVs, and home ...

Addressing the core issues of latency and integration in developing audio amplifiers for today’s smart cockpits.
