I want to know why the top-of-the-line CPUs and GPUs from Intel, NVIDIA, and AMD are all bragging about the fabrication process (7nm and 5nm) and trying to be consistently smaller. It's marketing ...
You are right in that the gain at 80 MHz is clearly not 100. Both the initial marketing points and the graph seem to agree on a gain⋅bandwidth of 45 MHz. There does appear to be a slight kink in ...
A quick intuitive way of looking at this circuit is that the voltage source, L1, and L2 can be thought of as a lower voltage source with a single lower inductance in series. This is the same as fi...
There is no direct way to determine whether the PIC is connected to a CAN bus. Part of the problem is that the PIC never directly connected to the CAN bus anyway. There is a transceiver chip like...
3.6 V is not the absolute maximum voltage. The table you show explicitly says "Recommended Operating Conditions". Therefore, running the chip up to 3.6 V is perfectly fine.
The flashing-light frequency shall be 90+/-30 times per minute. I don't know what could be more clear. This spec says that the light must flash 90 times per minute, ±30 times per minute. In othe...
I'll take it that you want this circuit to actually work, not just appear to work in some software simulation. In that case, it's about the circuit, not the simulator. A simulator is just one too...
It's been a while since I did 1-wire, so I don't remember the current levels. R18 seems rather high for supporting the minimum required voltage at the maximum possible current. Let's say for sake...
Your controller is too fast compared to the plant (the thing being controlled), thereby causing instability. The most obvious culprit is the 50 kΩ resistor between the controller output and the FE...
Now that you've supplied a link to the product, I can provide a different take on this affair. Your "UPS" is an Amazon Basics model described at https://www.amazon.com/gp/product/B073Q3BSPG/?th=1....
I see that manassehkatz has already given you a good answer and plausible explanation for what you observed, so I'll fill in a few other points. Your battery is 5 years old, so is getting to the p...
Such a domed button is usually called a "membrane switch", at least here in the US. As you say, the small metal bubble makes contact with something underneath when pressed. Advantages of membrane...
You say the only thing that will be powered by the ±12 V supplies is a comparator. The first thing I would look at is whether you really need the comparator to run from that voltage range. Presum...
Since you seem to be asking about whole batteries, not individual bare cells, dangerous effects should be limited. Consumer batteries made from lithium cells almost always include integrated prote...
I don't know about "best practices", but I make all my own library parts. I use Eagle, and the library parts that come with Eagle are quite inconsistent in things like pad shapes, what is shown on...
the original question is interesting and deserves a technical answer So go write one. That's your call, just like it's mine not to. We are all volunteers here, and are therefore never obligated ...
Safety of medical devices is not something you should be asking random folks on the internet about. The rules are stringent, for good reason. The clearance and creepage distances to line voltage,...
I have a similar problem when debugging firmware on a dsPIC that drives a flyback power supply. The switch isn't designed to be on for very long, as eventually the inductor saturates. Usually the...
What you describe is already allowed in Papers. See electrical.codidact.com/help/papers. The papers by Circuit Fantasist are well on topic. Presenting a concept in an accessible way is OK. I ha...
I agree that the particular question was correctly closed. Questions about protocol stacks aren't necessarily off topic. However, this one was because nothing about it had anything to do with ele...
One of the aggrevations Elsewhere were all the vandal and retribution downvotes. They never took the problem seriously. Now it's happening here. Andy was the latest target, twice, recently. I'v...
I recommend using native HTML for lists, and most other formatting for that matter. HTML gets around the ambiguity of what is an item and what is text following the list. The list isn't over unti...
Assuming nothing is broken or wired incorrectly, this is most likely the result of the opamp oscillating wildly. The average may still be about what it should be, so you might not notice with only...
It doesn't quite work that way. You are missing the fact that the current (which the magnetic field is proportional to) decays exponentially. You are also missing the resistance of the coil itsel...
RTOS A RTOS (Real Time Operating System) is much more than a bunch of interrupts. Most true dedicated microcontroller applications don't need any RTOS or any other kind of operating system. Genera...
