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 ...

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 ...

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 ...

Though sometimes taken for granted, designers shouldn’t overlook the intricacies of voltage- and current-feedback op amps—integral players in the analog and mixed-signal worlds. Op amps amplify tiny ...

We recently saw how certain audio power amplifiers can be used as oscillators. This Design Idea shows how those same parts can be used for simple amplitude modulation, which is trickier than it might ...

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 ...

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 ...

If you’ve ever glanced at the specifications sheet for an amplifier, one of the things you may have noticed is the amplifier’s class. Typically denoted by a letter or two, the most common amplifier ...
