As part of a phosphorescence detector, [lcamtuf] has been working with photodiodes. The components, like all diodes, have some capacitance at the junction, and this can limit performance. That’s why …read more Continue reading The Disappearing Capacitor
We always admire when companies produce useful tools or documentation that aren’t specific to their products. For example, consider LTSpice. Sure, it has the company’s models baked in. But there’s …read more Continue reading Analog Engineer’s Pocket Reference Needs a Big Pocket
With the incredible variety of projects submitted to our Op-Amp Contest, you’d almost forget that operational amplifiers were originally invented to perform mathematical operations, specifically inside analog computers. One popular …read more Continue reading Op-Amp Contest: Virtual Ball-in-a-Box Responds to Your Motions
If you’re a child of the ’80s or ’90s, chances are you’ve spent hours tracing out intricate patterns using the pens and gears of a Spirograph kit. Simple as those …read more Continue reading Op Amp Contest: Generate Spirograph Shapes Using Only Op Amps and Math
Brains are the most complex systems in the universe, but their basic building blocks are surprisingly simple — the complexity arises from billions of neurons, axons and synapses working together. …read more Continue reading Hackaday Prize 2023: Explore the Basics of Neuroscience with this Electronic Neuron
Water cooler talk at the office usually centers around movies, sports, or life events. Not at Hackaday. We have the oddest conversations and, this week, we are asking for your …read more Continue reading Ask Hackaday: Split Rail Op Amp Power Supply
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 …read more Continue reading Analog Anoraks: The Op Amp Contest Starts Now!
The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of …read more Continue reading From Nanoamps to Gigahertz: The World’s Most Extreme Op Amps
Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to heat up a soldering iron or turn on a bench supply. This time, we are going to …read more
