As we’ve discussed, the SPICE simulation is only as good as the op amp’s macromodel, and other components, parasitics in the printed-circuit-board layout, and poor power-supply bypassing can ...

The PI software algorithm is popular for closed-loop control, as it’s a direct software adaptation of traditional op-amp circuits. We developed a digital controller for educational purposes (Fig ...

We thought it was time to give the analog side of Hackaday their chance to shine, and what’s the quintessential analog IC? The op amp! Whether you’re doing tricky signal conditioning, analog ...

Given the role of electronics in engineering and technology, laboratory experiments and circuit simulation IT tools are used in their teaching in several academic institutions. This paper discusses ...

Author’s note: This article shows how to derive circuit gain equations via a signal flow graph. With practice you may be able to write a gain equation by locating signal paths and loops in the ...

Part 3 examines how a varying power supply voltage effects the output of a basic op amp circuit. Part 4 offers a cautionary tale on using op amp macromodels – what you see in your simulation is ...

This very sturdy-looking circuit provides an easy way to configure the op-amp for testing in inverting, non-inverting, and transimpedance mode, selecting from a range of feedback resistors, and ...

Analog signal processing has long been a cornerstone of modern electronics, enabling the manipulation and conditioning of continuous signals for diverse applications.
