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 ...

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 ...

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 ...

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.
