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 ...

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 ...

Especially for applications with high source impedances, the current noise multiplied by the source impedance could reach or even exceed the level of the op amp’s voltage noise, and should therefore ...

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 ...
