say that materials should be small and focused There are many many theories of how to best present information. Any one or two particular opinions aren't really relevant, especially since there i...
At some point the MOSFET approach will lose to diode if current is sufficiently high: The drain-source resistance will cause the forward voltage drop to go up linearly. So picking a MOSFET with ...
While doing some reading on RF designs I ran across this paragraph: I have never designed an RF circuit, but all the PCB trace antennas I have seen on development boards are square. For example,...
How can we extract a DC signal from a mixed signal? You use a low-pass filter with a cut-off frequency that is significantly lower than your lowest AC signal frequency. If you need better filt...
The question being asked Ultimately, I want to know why the output voltage wasn't the expected (via calculation) 11.72V when the estimated drop-out voltage at the ~0.1A load was about 200mV. The i...
I have a 4-20 mA digital air pressure regulator which is controlled by and reports its pressure by being the current sink in two independent 4-20 mA current loops. Our control system utilizes Anal...
Building on a previous question about terminology, I am trying to arrive at a solution to connect a digital air pressure regulator that sinks current as part of its 4-20 mA current feedback loop to...
One of the first things you should do is provide a connection for the scope probe ground. If you think you'll be regularly looking at signals on this board, then one of those little loops or pins ...
calculate the voltage that will center the magnetic field of a coil This is not possible since the voltage has no effect on the position or shape of the magnetic field. The position and shape are...
In the auotmotive context, does it matter where the fat load-dump grade diode is placed in relation to the MOSFET so as to protect it from both fast positive transients and the longer load dump ? ...
10Hz to 10Mhz is a wide frequency range, it would be very hard to cover that whole range in the analogue domain, as you have discovered analogue oscillators that can span more than a factor of abou...
I have also designed and ordered a PCB It seems rather pointless to ask after you've already ordered the board. only uses THT-components That's just plain silly. This is the kind of thing that ...
I am working on routing a microprocessor to two identical single data rate (SDR) SDRAM chips that are PC166 compliant, particularly Alliance AS4C16M16SB-6TIN. The 16 bit SDRAM chips are combined t...
I am using the AD620 as instrumentation amplifier to amplify the body's ECG signal. An ECG is a differential signal (measured with two electrodes) and I want a differential gain of Gd=1000 . The ...
I am an electrical engineering student and I just finished designing an ECG-amplifier circuit. Here is the schematic: - It is fairly simple. Initially, there is a 1st order highpass filter. Then...
I have a small solar panel rated for 6V/DC, 150mA. I know that those specs are under ideal circumstances, and I would like to do some measurements in different weather conditions to see what I can ...
Following a lot of discussion in comments, we're going to split this request: Capitalization changes: these were previously discussed and we'll make these changes for you. We can do this at t...
Thanks for asking. In my view, if it's something you'd first think of asking an electrician, it's probably off topic here. That includes what type of cable to use, whether it should be in a condu...
*Learning about EMG as a part of our research. My team has at least some experience with electronics that is worth mentioning, but don't have any experience with EMG/bio-potentials. Most EMG hardwa...
I would like to save some costs with ideal diode controllers. Basic requirement is for the diode controller to block overcurrents (short circuits) in both directions. The MAX16141A IC can do it a...
I'm not very familiar with this site but was pointed to it by a comment. That made me wonder, what exactly is the scope of this site when it comes to residential wiring? For example, Basic wiri...
Feel free to provide a list here and someone will go through and update them. For instance, I've just renamed [led] to [LED]. Please include both the old tag name, the new name, and ideally an expl...
67 tags deleted, 10 with posts still attached left alive.
I've just finished a first clean-up of the tags pages, where I consolidated tags, provided synonyms, wrote guidance text and defined some hierarchy. As a result there are quite a lot of "dead" tag...
I am trying to figure out what is causing an Allegro A2982 source driver to burn up. The source driver (A2982) is connected to the coil of a Panasonic TXS2-9V relay. The source driver and coil ar...
