 24 Dec 2004 5:12 how to become a mixed-signal IC designer? |
|
|
|
I will go to ShangHai for mixed-signal IC design.Please give some advise on how to become a eligible mixed-signal IC designer.I have zero experience in this area but some discrete analog circuit design.
Thanks and Happy Xmas!

first of all ,
go through "signals and system"
then learn some Digital Design Tools and learn their design flow.
Last but not least, do some real stuff.

Why, I wonder, should "signals&systems" be considered first?

| I guess what qslazio means is to have a better understanding on 'real' signals, analog and digital.

In my opinion, for Mixed-SIGNAL circuit design, a solid knowledge on some classical theories in "Signal and System" and "Digital signal process" is required for a good designer,
and sometime the circuit is easy to build, but the theory behind them is difficult to understand.

| I suggest you can start from data converter design

After you have designed some circuits, you will found the "signal and system" and DSP is very important!
If you have no knowlege of it, you can not begin you design.

besides that, as a mixed signal IC designer, should have a battle with noise and non-linear.

I think, as a mixed signal IC designer,1sh step you should design an opa well by yourself.

of cause noise ,power dissipation ,linearity ....like your friends(enemy) will presence you without your invite when designing u chip.

Working hard in digital first ( the easy part), 2-3 years, and starting to do analog after that.
Your first contact with mixed will be in digital world, working on memory!
Your 2-nd contact will be on signal distribution, wher cross-talk and other problems related to this will appear.
After that you will find I/Os! This is realy nice!
Don't start with mixed! I know some people which do this, and the results are not so good.
Be creative.

| for being a good mixed signal designer u must have agood feel of analog integrated circuits such as opamps,current mirrors and comparators.u must also know digital design and according to present and future u must also have good knowledge of deep submicron issues

for the digital part, does it mean the custom design? or like the ASIC design, using a lot of tools do HDL and synthesis?

Added after 8 minutes:
so this means i better to take DSP course now. (I am in school to learn the circuit design now.) Also, do you think it is useful to take the "introduction to communication system" course to do the circuit design?

No doubt ,fundamental knowledge in signal&systems is very important,
but the knowledge in semiconductor and circuits is more important,
you can have experiance after 3 months
goog luck!

Find a job, learn how! you can start to design the mixed signal circuit step by step,
But if you only learn it from the book, it will be very difficault to be a good designer.

which course usually at school to teach system and signal? DSP?How about control system? about digital design, you mean customer design. is that right?

I agree with gabi71ro 100%!
Indeed, it is not so easy to have the chance to touch the desired projects and learn from them!

| try to find a mixed signal designer that looks similar to yourself. kidnap them and begin going to their job in their place - keep them in a closet, so if you recieve a design project you cannot complete, it is convenient to ask them.

| I should say with out the basics of the Signal Processing the Analog Design itself seems difficult. After spending one year on DSP in academics I turned to Analog Deisgn and it seems that any good simulator should use DSP techniques for accurate results. Simple DFTs may not work often due to their lack of accuracy with the sample sizes. I dont know much abt the Mixed Design but you will never have a feel of a good designer without good knowledge in DSP.

| To do some real case is the most important thing. Such as ADC/DAC, PLL, etc.
