- How to simulate a common emitter bjt amplifier in qucs 0.0.18. Simulating the frequency response, DC bias, and transient response. In this video I'm using version 0.0.18 of qucs. Qucs is completely open source and can be downloaded here qucs.sourceforg...

Excellent! It was very helpful in assisting me successfully replicate the "correct" qucs Example for Tunnel.sch. Now I can produce the same graph as shown in the qucs example. The published example may have a typo in it. Plus with my bad eyes, fat fingers, beginner's faulty knowledge/learning curve, it was a real 'learning' experience. But your presentation gave me the hint to look for a qucs process based solution.
Struggled for a couple days failing to get my sim to work. Got it going after watching 7 minutes in. Thanks a ton!
Very helpful video! Thanks!
very helpfull thankss man...
Compliments! I found his lecture very informative, and I finally had the chance 'to figure out how to run envi program. Great my interest in the subject treated by you.
If you are not disturbing, and I wanted to ask what 'the latest version of Qucs and possibly from where i can download it.
Thanks so much
+Ser Marone The latest stable release of qucs is 0.0.18 but 0.0.19rc1 is also available. Qucs is completely open source and can be downloaded here qucs.sourceforge.net/download.html
THANK YOU.
Thanks for informative video. I have a question ,How to import the PTM models in QUCS? I am trying to download a FINFET model and simulating IV characteristics of the transistor.
Can you provide a link to a model you're trying to import?
Hello !, I have a question. How you can see the harmonics of a wave? That is, as I can do the fourier analysis to see the graph of amplitude versus frequency.
And another question, how I can put several expressions in the same equation ?. I saw in some examples has a built qucs and not how.
You can do a Fourier Transform using fft() and/or dft() functions. More information about these functions can be found here qucs.sourceforge.net/docs/tutorial/functions.pdf
There shouldn't be a problem doing multiple expressions in one equation block. Can you give an example for a problem you are having with it?
thanks for the information!
What should press keys to add another equation ?. For example, within
qucs, you are an example called Ic_osc and has two equations.
Wrong dependency is displayed in tabular format output. Pl let me know the meaning of this message. Thank you

I have nothing on my graph , only able to see the DC Bias on the SCH
Low pass characteristics are not found to calculate bandwidth.
rotita simulation tools este tot timpul oarba ..ceva nu functioneaza la acest soft
down with PSpice!! and hurray for open source applications!
is entering by hand the only way to get the transistors to work with?
no look to the library you will find some of the most used components named and sorted for you
Hertz! From “ Heinrich Hertz”. One cycle per second
Hey, what are you using as simulator, qucsator or ngspice?
I hate Pspice as well and my professor only uses that shit haha. Nice video though, helped me a lot.
Good job! Id feel better about Qucs if any real development was going on over the last 10+ years but many thanks to those that have put hard work into it.
Very nice video. thanks for making it.
Useful Video!
is it possible to simulate lissajous figure with opamp on it.
Sorry again, I can not install the latest version qucs, as in the download folder (zip), from the official site, I never find the setap.exe file.
Kindly do I know how to install qucs for windows 7?
+Ser Marone The setup exe if available on sourceforge. The latest stable is here sourceforge.net/projects/qucs/files/qucs-binary/0.0.18/ and 0.0.19rc1 is here sourceforge.net/projects/qucs/files/qucs-binary/0.0.19-snapshots/ The 64 bit 0.0.19rc1 setup exe is called "qucs-0.0.19-rc1-win64.exe"
Download the file , extract it. Copy the extracted folder and insert in the C drive where the programs reside. Make a copy of the ".bat "file in there onto the desktop. Double clicking it (depending on your mouse settings) will open QUCS for you!

Hey
Can you please give some information about differential amplifier using npn transistors? I have a project to submit and i have to do that on QUCS. If you can convey the circuit and the values it'll be very helpful.
Thanks
I'm not perfectly sure what you are doing but here is a simple differential amplifier circuit made with two npn bjt transistors. s000.tinyupload.com/index.php?file_id=06452015731172121927
Hope that helps
THANK YOU SIR!!
You literally saved my ass!!
The link was extremely helpful.
Keep up the good work.
All the best!
Thanks a lot
In other words, you have no interest in learning to design even simple circuits or learning to use a great tool for work, so you beg someone to do your schoolwork for you so you don't have to learn to think and do things yourself? Why not find something you really like enough to work with, and major in that instead of engineering? Then you can be happier and make money, too. I don't understand guys like this, and there are a million of them.
please make more tutorials on QUCS
Anything in particular you'd like to know/see?
Please explain every available tools inside this software....and. Specially simulation tools..
I'm having problem with simulation and Dc bias calculation....
Please make many videos more frequently...
Make different projects and simulate them and share with us..
Please give your email...I need more help with QUCS.
