How to simulate analog circuits on linux ?

I'm currently using fedora linux, can't find any good software where I can simulate my analog circuits. I tried using Pspice through wine on my pc I'm not able to simulate the circuit after designing it, probably an issue with the wine configuration or something. Anyone suggest me a good software for these analog circuits for linux.

If you have several years of work experience, would you choose in-person MSc program (going from full-tile to part-time and thus salary cut in a country you live and work) or attend online in MSc in another country (full coveres financially) in another country you dont plan to work or live?

As the question suggests, I have the opportunity to attend a prestigious university's MSc program in the country where I live and work, but it would require me to go part-time and take a salary cut of approximately 25%. Alternatively, I can attend an online MSc program fully funded at two mid-level U.S. universities, UF and MSU. I am struggling to decide which option to choose, as both universities offer almost the same courses.

Clarifying some really stupid circuits questions after 6 years out of school

Image

I'm going back to school for my masters in ECE with a non-ECE background (bachelors in different engineering field) so I'm getting dropped into the deep end with an analog circuits class. I have a few super basic questions about this inverter circuit homework problem:

NMOS is at the bottom, source is at lower potential, so it should be the very bottom of this diagram. Do I assume it is at 0V, making the gate to source voltage 0.7V?

The output (?) voltage is 1.5V, so I assume that's the voltage for the inner two (PMOS source, NMOS drain) terminals?

The effective voltage for NMOS and PMOS is simple when they're on their own, but I can't find any information about calculating when they are in a CMOS together. Does this change anything about their V_eff?

What is the extra connection coming out of the "gate" for both sides? I assume it's the body in a 4 terminal device, I'm just sort of confused on the layout and how it's drawn.

I'm trying to find some good videos or resources to catch me up on this (the course is more focused on circuit design, not analysis) but I'm struggling to find the right keywords to search because I haven't found much good material.

Thank you!

Where can I find more exercises like these?

I have a logic circuits exam that comprehends from bool's algebra to counters. The textbook related to this course is written by my professor, but not every topic he asks at the exam is into the textbook. I can't find more similar exercises and the ones he provided aren't enough.

Here is the first kind of exercise:
Given the function h(x,y) = x[y+f(y)], prove that:

  • h(x,y) doesn't depend on the value of f(1);
  • prove that if f(0) = 1, h(x,y) doesn't depend on y;

This kind of exercises is usually solved using Shannon's Expansion Theorem.

The other kind of exercises that I need is this one:

Given X = [x_2, x_1, x_0] a non negative natural number:

  • design a combinational logic circuit that calculates Y = X^(2)

This kind of exercises usually asks to calculate some kind of arithmetic expression, sometimes with shifts, sums, power or logarithms. The only components I could use are full adders, half adders, decoder/encoders and multiplexer/demultiplexers.

I can't find any additional resources nor exercises that could help me passing this exam, since I failed it many times :')

Any suggestion or help will be much appreciated

How to make sure that I pass technical test?

Hello, it is internship season in my college so companies are recruiting. The most important shortlisting step is the Aptitude test (It is called an aptitude test but almost all of the questions are technical.)

I'm finding it hard to clear the test. A huge chunk of the people who get selected cheat during the online proctored exam. How do I ensure I pass the test and increase my chances of getting an internship in this situation?

Can someone tell my why the base emitter relationship is wrong?

Hey can someone look at this post and tell me why I am mistaken. I am looking at the base emitter voltage versus emitter current plots for a given collector base voltage. I am having trouble reconciling different pieces of information in different textbooks (Boylestead and Sedra/Smith). If some BJT expert could have a look I would appreciate it, thanks!

Technical University of Munich (TUM) for Electrical/Computer engineering?

Hi all, I have an option to do a master's degree in Europe, but I want to eventually work in the USA for some time. I am not American.

Is this University on any employer's radar at all? Or is it just another random name to them?

Are foreign degrees looked down upon, or seen favorably at all in the US?

Thanks so much in advance!

Trying to remember a protocol/technology

So my apartment gate opener is one where you enter a code, it emits a tone, and that opens the gate(I think!). I want to clone this tone, I am just losing my mind trying to remember the name of whatever this type of communication is.

I know this is possible, I did something similar as a college design project by just playing back a .wav file over a speaker, I just cannot for the life of me remember what this particular technology is called.

Any thoughts on what this is? It emits a tone, kinda sounds like a dial tone? I remember something about one frequency being a 1 the other a 0 etc.

Beginning of career struggle, what should I do?

Hi everyone,

I'm an engineer working in analog design in the semiconductor industry, and I’ve been feeling pretty lost and unhappy in my career lately. I've been with my current company for about a year, and while I’ve gained valuable experience, I find myself constantly stressed and struggling to achieve a good work-life balance.

To give a bit of background, I’m based in Central Europe and have been in the field of Electrical Engineering for around 1.5 years, including some experience while finishing my degree. My current net salary is in the range of 2,000-2,500 euros per month.

I’m currently considering a few options for my next steps. One option is to look for a different job within analog design, staying in my current specialization but hopefully finding a company with a better work environment. Another option is to explore other areas within Electrical Engineering, potentially shifting to a different part of my field that might offer better balance and growth. Lastly, I’ve been thinking about switching to a different career altogether, though I'm not sure what that would look like yet.

My main concerns revolve around finding a better work-life balance, as I want a career where I’m not feeling constantly stressed and can enjoy my life outside of work. I’m also looking for growth opportunities, somewhere I can grow both personally and professionally without feeling drained or unmotivated. Future remote work options are important to me as well. While I know early career stages might require more office presence, I’d like a path that could lead to fully remote work or a hybrid setup with a maximum of one day in the office per week. I prefer the comfort of working from home over traditional office environments. Lastly, maintaining my current salary level is important, as I would like to avoid a decrease in income.

If anyone has experienced something similar or has advice on navigating these options, I’d really appreciate your insights. Any advice on remote work trends in engineering or similar fields would be especially helpful.

Thank you!
