Is it too prestigious to get a PhD fellowship? I was told that it is too much of a competitive award and will be tax free (for 1 year). I am considering joining The University of Arizona even though I have other fully funded offers from higher ranked universities. For instance, Virginia Tech (GTA), Colorado School of Mines (GRA) and others. I have possible opportunities to get offers from USF, UCF, Arkansas.
My professor here in UArizona is also very good and humble. Am I doing the right thing to join here leaving other schools which are much higher in rank and reputation?
To derive the ideal diode current equation, we work with the minority carriers and solve the drift-diffusion equation in both n and p sides. Is it possible, either analytically or numerically to get the current, from majority carrier drift-diffusion equation? Thanks.
Hello, im a hs student that wants to study ECE and possibly finish it early. For physics i know circuits,cells,heating effect,lenz,faraday,capacitance,the smith chart, emf induction etc. im taking advanced calculus (ode, pde etc.) For coding i know basic python and C (from working on my arduino) and have a good understanding of logic gates and currently trying to figure out binary arithmetics and memory.
What else would you advise for me to learn before starting ECE? (except fourier transformations)
Been googling how to implement this using logic gate, but I can't seem to find any. Is it possible to implement event-driven sequential logic circuit using d flip-flop? May you please share resources about this? I have already created moore FSM, but I don't want to use clock.
What exactly does a physical design engineer do? Based on my understanding he is responsible for the whole backend flow. He uses tools to automate the whole back end processes.
RTL to gtech netlis
Gtech to technology dependant netlist
Technology dependant netlist to routed netlist
PNR
CTS
STA
So he doesn't have to draw the layout manually? His skills depend on how well he uses an eda?
If that's the case why dow we draw schematic and layout manually in some other designs?
Also doesn't synopsys have a tool that specialises in schematic capture?
I'm an international student currently doing masters in Electrical Engineering at NC State. I'm looking for internship opportunities for DV/RTL Design roles but the search is not going great. I have applied to almost 150+ applications and I'm not getting any call from the recruiting manager. I'm also looking for research opportunities in case if I'm not getting an internship this summer. The process is extremely tiring and I'm losing hope in myself. Not sure what to do next :(
I have a GPA of 3.22. Does having a high GPA favours in getting more interview calls?
As of now I have a degree of MS in Electrical Engineering while my peers are having a degree in Computer Engineering and they are somehow able to get interview calls. Does having a different degree hamper your chances at getting noticed by the recruiter?
I would love any kind of tips/help for moving forward. I would also love some insights on co-op and how should I be better prepared for full time roles in the future.
Hi Folks,
FADE IN:
I am a ECE graduate "PASS"-ed out in the year 2020 since then I worked in IT industry on ERP software technically I am not even a software developer ..more like a mere application developer and also worked as a writer for two years but it is not paying me any bills rather caused severe health issues that sucked out my passion to write ... ( cough in silence.)...you can see it's still there but it's slowly fading out ....finally reaching it's own threshold.
FADE OUT
"CURRENT"-ly, I quit my job in jan since then I am just thinking about career on what to do, Back then ...3 years ago while I was still in my STEM program... I remember I was good at VLSI designing that was done and also those tiny Microcontroller programming that I have done on 8085/ 8086's ....If they need any doubts...Iwas the go to guy in my VLSI/ MC LAB's...I used to pass on the outputs of the problem sheet that were there in the LAB curriculum...but I never focused on ECE side later don't even know why...may be I had a fear to work hard back then as I got a IT job as soon as I graduated.
Now the suggestion I would like request you folks is....Is it too late to "SWITCH", want to restart my career again.
In life in general money isn't my top priority, Kindly suggest me some online resources to get back on or any masters programs you folks would recommend to take....my mom says go and study abroad we"ll arrange the loan but I am adamant on going at this current situation, reasons being too crowded....ppl are more behind money than skill ...if you guys suggest any good colleges for masters in USA/ CANADA/ UK...will select one under my budget and will likely to try to complete 2 Semester syllabus while I'm in my country so that I can be prepared for the worst case scenario.
TL; DR: Three years ago 24M loved something but went with something else but still remember the past love ....regrets on choosing something else hoping to get back on what he loved.
Hi all, not sure if this is the right sub for this so feel free to redirect me if needed!
Anyway, I’m looking for a sensor that can detect and count acousto-magnetic EAS system tags
I intend to use the sensor to count the number of ice bags a customer removes from my ice merchandiser
At first I was thinking of using a photoelectric sensor but it would also track the amount of times someone would reach into the merchandiser.
I guess I’m looking for a combination of a metal detector (for the AM tag) and a diffuse sensor? Any guidance helps!!

Hello guys, It would really be helpful to get your opinion. I am an international student who got admits in ECE/EE at TAMU and Columbia and the results for EPFL will be out soon. All the three universities are very good but I am inclined to Europe because of easier visa procedures. But my mind is swayed because Columbia is an ivy league and TAMU has better ROI. I have also been hearing that job market is better in Europe than US (contradicting views are there) and now I am all confused. Which one to select? My specializations include computer engineering/ control systems/ bioelectronics. Which will be a better place to go?
I am a recent grad, and am curious on the possiblility of transition from a test engineer to an embedded firmware/software position. I have my first and only job offer as a test engineer for embedded systems, where I would work on creating a test framework and some automation stuff, and with some microcontrollers. But in the long term I want to work on embedded SWE or firmware. Is this a good place to start my career or should I keep searching if I don’t want to get stuck as a test engineer?

I'm currently in my second year in a Tier-2 Private college in ECE branch, i really love all my core subjects and have real interest in the topics taught, i have a decent CGPA of 9+ and have no minimum attendance criterion in my college.
I want to pursue jobs in my core sector but I lack the guidance needed. Everyone just says that there's not much scope in core so i should just study DSA and sit for placements for IT companies. I have knowledge about C/C++/Java and Python and I've made niche hobby projects in all of these languages the only thing left is to do DSA.
So, I really need some experienced advice from someone in the core sector as to what the current market is like and the scope for jobs in ECE.
If you all could suggest me ways to enhance my knowledge in my field please please let me know, i currently am learning Arduino.
I have the summer break coming up, looking forward to your responses.
Thank you for reading this far :)
Hi Good Day
if i have multiple HX711 ADC for my load cells (i have a project relating multiple weighing scales) can SCK in HX711 share one clock? i know Vcc and Grnd can be shared but can they share one clock?
Thank you for responding
I'm about to start a new job in cpu verification. Is it possible to switch internly to performance modelling? How can I build my skillset for such a change?
u1: iobuf
generic map(
drive =>12,
iostandard =>"lvcmos33",
slew=>"slow")
port map(
o=>data_s,
io=>data_in,
i=>'0',
t=>en);
Who can help me understand this iobuf and how to set it up in my Vivido software?
Hi, I am currently holding a BSc in Electrical and Electronics Engineering (completed) and will be starting my PhD on the coming fall in the US in Analog/RF. Will I be able to find a summer internship on coming May (Summer 2024)?
After I power on the encoder, the encoder status LED light shows red and the encoder is not taking counts. I looked through the manual and couldn't figure out how to troubleshoot the issue. Has anyone had this problem before? What's the root cause and how did you resolve it?
So AC power is what we will be beginning this week. I looked at the slides and saw RMS power. I really do not understand the point of it, but I don't blame myself because I looked at it for 5 minutes.
What I'm kind of gathering is:
RMS turns the AC voltage or current into a constant (not time dependent anymore). By dividing by square root of 2, you find a constant number (a length of a range...???), which is somehow relevant to the current, voltage, whatever it is.
Wherever I'm confused, plz correct me if you don't mind. Anyone who reads and especially anyone with insight, I appreciate you lots. Thanks
Me:
I would like to switch to SoC / Processor Verification (European market), but I am meeting a lot of resistance from breaking in this industry.
It's kind of a chicken-egg problem: the positions I find are either internships for students, or Senior-like positions requiring 3+ YoE in the field, but how the hell is one supposed to make those 3+ YoE in this field? All the companies I could find on Linkedin (across europe) - Intel, AMD, Qualcomm, Infineon, but even startups - have the same strict requirements.
It seems to me that the move I'd like to make should not be that big of a deal, after all I would still be a Verification Engineer using SV/UVM and the same principles of verification, but on a different tech stack: from networking/DMA IPs to SoC/Processor domain.
However, it seems that such a moderate change is encountered with high barrier and resistance from the job market.
My intention is not to rant, but to really ask for an actionable advise on how to prompt and make the shift of career happen:
--- EDIT ---
TL;DR
How does one gets exposure in a field which requires "experience in the field" as an entry level barrier?
I want to experiment with IEM tuning with impedance adapters, so I am looking for a schematic to understand how these things work in the first place. I am somewhat experienced in electronics and quite experienced with soldering, so it will be a fun project for me. However I am not sure the schematics I found on google images and some websites are correct or not.
So, If anyone can help me with the schematic of an actual impedance adapter, please do. Thanks.
so am using my laptop to power up my arduino. and i uploaded the code with no errors. however when i connect servo motor my arduino (chinese clone) disconnect immediately.
what could be the problem here ?
