As the others said, there is no definite answer to this. But here is how we do it: There is a global schematic library and a global footprint library. They have the components we use and have the ...
I've done similar things on UART lines, but for significantly lower baudrates (9600 etc) than traditionally used on most CAN buses. It's also easier to do when you have 5V guaranteed to be well-ov...
Based on reading the All About Circuits article on IEPE sensors there are two general types of circuits integrated into this class of sensors: voltage amplifier and charge amplifier. This question...
Vias are used to move up in metal layers. The contacts of the transistors can be directly connected with metal 1, but if you want to use higher metal levels, you move up to them with vias. For exa...
An induction motor with its shaft held still will mostly look like an inductor with a series resistance electrically. However, there will be some issues: It will be difficult to guess the inducta...
What effect does an oscillator potentially have on a SPI clk signal if the oscillator is on the top layer, with GND and VCC layer in between on a four layer board. I know running it on the same lay...
It's hard to answer your specific case since you didn't label the layers in your picture, or which traces are doing what. That said, a few traces crossing each other on different layers is not muc...
What you are proposing may be okay (depending on other specifics of the design), but your proposed 4-layer PCB stack-up looks like a compromise. Clock is a high speed signal, and so is SPI dependi...
I only address this point: Are there some other way how to do this which I have not covered? Yes. Instead of using boost and buck converters, you can use integrated charge pumps. They don't u...
Hi, how can I use can bus monitoring through a simple led without disturbing the can line , I started with a diagram found on this forum, I need your help to correct where necessary, I want to use...
You'll need a differential comparator, something like what was suggested in here. But I'd look for a proper Canbus Rx and extract that to convert to single ended one shot to pulse for activity.
That depends on whether you are just building something for yourself, say a prototype, or if you are designing a product for mass distribution. In the later case, you are subject to probability law...
My Answer: There are only practical reasons for a representation with Ib=const. These characteristics are primarily used to determine the DC working point (Ic_o, Vce_o) - together with the working ...
I think this could be on topic if done carefully. We don't want this to devolve into a popularity contest of everyone's favorite features. Answers also can't be about opinions of which features "...
What happens to the overall accuracy of a resistor if I implement it as multiple resistors in series or parallel? For example, can I get better than 2 kΩ 5% by putting two 1 kΩ 5% resistors in ser...
The default scope in this EE community pretty much went with the same scope as the SE site. For now. These sites are new and most communities are still struggling to come up with what's off-topic ...
Eureka! thanks to the article cited in the question, I've finally understood the matter. I will describe here the general procedure for computing the network parameters of a grounded two port devi...
Baudrate is most often used to mean payload data bits/second. Simply picture a manchester encoded protocol, where each data bit corresponds to 2 physical bits in the raw data frame. If you have a b...
[In addition to the answers which have already been posted.] A current sensing circuit like this lends itself to another scheme for ESD protection, which uses only one TVS. Only the line in which...
Hello, I am designing 1/4 WL strip antenna for a bluetooth chip and i had some questions regarding the 50 Ohm feed line. Right now I am using a Nordic-recommended 1.5mm trace width and a 23mm + 4mm...
Despite there are many filter calculators available on the web, I still have difficulties to translate what I need into calculator design parameters. For my application, I need ideally a high pass ...
A voltage source is "heavily loaded" when something is drawing a large amount of current from it. "Large" in this context is relative to what the voltage source can deliver, or perhaps relative to...
Consider this statement "A voltage source is heavily loaded",what does this mean? I mean that whether the load resistance is high or there is huge drop in source voltage at load due to internal res...
I am having a difficult time picturing the flow of current and the role of the capacitor during the OFF time of a buck converter. Here is my understanding so far. During the ON time the magnetic fi...
A switching power supply already is inherently a filter. Current is coming thru an inductor, followed by a capacitor to ground. If you are asking what additional is usually done to filter out chan...
