What every RF design engineer needs these days is a good all-purpose IC RF amplifier. You don’t want to have to design basic circuits like this yourself. Yet the need is always there for a gain block ...

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 ...

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 ...

With the ever changing requirements in the audio market, there have been many advancements in audio amplifier topologies. Knowing the types of audio amplifiers available and the characteristics ...

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 ...

When using an active front-end amplifier to drive a high-speed converter, designing an anti-aliasing filter (AAF) can be a difficult task. It’s important to get it right because anti-aliasing is the ...

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 ...
