Reading a Tesla Wall Adapter installation manual , their brand of an AC EV charger, chapter about “Ground Assurance” and here is the quote from there: Although the equipment can work with L1 and...
Which topology is preferable? The one below because the LED driver is less likely to produce instability and, if it does, you can always tweak C4 (upwards) in order to kill-off the potentially...
Some gentlemen decided to throw a hook with wire over 750kV lines in Belarus. They survived, however, I find in interesting to find out why. Assuming the connection to Earth was solid, there would...
It's got nothing to do with the MOSFET's miller capacitance. Miller capacitance causes problems in common-source circuits but, your circuit is common-drain (or source follower) hence, with a steady...
What part of the absolute maximum ratings for the A and B data lines do you think would be protected by 33 volt TVS diodes: - If the chip is powered from a 5 volt supply then you use 5.6 volt TV...
That circuit is drawn rather obfuscated, but it does seem to make sense: Start by looking only at D1, D2, C1, and C2. Pretend D3, C3, and D6 don't exist. Although not drawn very well, this is ...
I'm designing a robust 1-wire output for an IoT board. The interface should be able to withstand high voltage. Mainly the same voltage level as the board power supply. That's 12V to 36V DC. The p...
Do common-source JFET amplifiers have an advantage over common-drain? The JFET would be in a low noise photodiode amplifier. The signal is 100us pulses with 10us raise times. Here are the schema...
Yes, votes on meta should not factor into rep. Meta downvotes indicate disagreement, not that you're a terrible person, have the IQ of a garden slug, and cast dispersions on your heritage like the...
I've done a lot of work on tags lately and I'd like to share with the community some thoughts about the way tags should be named so that maybe it could become part of the FAQ and so hopefully lead ...
I just submitted a proposal to DuckDuckGo here for a new "bang" for their search syntax. If approved: !coddee search_term will trigger the following URL: https://electrical.codidact.com/posts/se...

I was looking for guidelines of how to select appropriate cables for applications (I am interested in DC), I found IEC 183 standard which talks about high voltage cable selection for AC. Also, the ...
Starting with your first circuit: It seems a little klunky, but should work. I don't like the D1 and D2 diodes. The reason I placed D1 is to avoid triggering the mosfet with very low voltage li...
synopsis Achievable by using a rail-to-rail op-amp. A small bias on the non-inverting input improves the transient response of the op-amp. That’s the second circuit in the O.P. I use such top...
In my PCB design, I have 0402 components connected to polygons. To reduce the risk of tombstoning, I connected them using thermal relief. My guiding principle is that if heat dissipation is not sy...
The main point is that you need thermal symmetry between the two pads of a small package. You want the solder paste to melt at the same time between the two pads. Molten solder has significantly ...
For power polygon that primarily carry DC, how critical is it that it is located above a ground plane? If it is important, how crucial is it that the polygon completely overlaps the ground plane b...
If it is important, how crucial is it that the polygon completely overlaps the ground plane beneath it? A power polygon can hang off the side a of a power plane. Complete overlap isn't crucia...
Rosenberger 23C25D-40ML5 specifies 500V RMS rating: Looking at the recommended landing pattern you can see that the distance between the signal landing pad and housing of the connector is 0....
During FCC (or any other EMC) testing, the manufacturer will use some antenna(s) and only those antennas will be the ones approved. If you modify the antenna or use one which wasn't used in the tes...
Looking at Texas Instruments opamp OPA2211it mentions GBW of 80MHz at a gain of 100, and 45MHz at gain of 1: Looking at the bandwidth graph from Figure 10 in datasheet: It looks like 80MHz is...
Those batteries must be for powering electronics that receives commands from your controller or remote. They don't have anywhere near the energy to raise something like the headrest of a normal be...
No, none of your signals sound like "high speed". However, that doesn't mean you should ignore high frequency noise issues. If you can dedicate one layer to be mostly a ground plane, that would b...
Your first circuit topology makes sense, although some of the part values are questionable. How the circuit works R37 provides the bias supply for the condenser microphone with a predictable impe...
