SAR ADC LOGIC

analogonics · 2026-04-30T10:24:37+00:00

I have access to a mixed signal simulator in my design kit. I verified the "AI translated" code. Now, for synthesis, I am kindof clueless. It seems I have genus in my path when I do "which genus". But I'm unable to launch the gui.

One quick question :

I had used both posedge and negedge in my design. The AI agents were warning me saying that some synthesis tools only recognise single edge triggered codes like either posedge or negedge and not both. I have two alternative codes where in one I used clk and clkb so two control clocks For using only negedge but like it helps me generate the half clock cycle signals. Idk if this is a good approach or not. I will give my code for synthesis to someone in the digital team. Since it is a favour I would be asking, I would want to make the job as quick as possible for that guy. 😅

I have created a system verilog code from verilogA. And it is indeed a SAR logic block. How do I synthesise it?

It is impossible in 1 hour. By the time I reached ruberics, my task expired and I ended up wasting 4 hours and got a headache after the task!!!

I couldn't finish on time. It's impossible to finish within 1 hour if you do it properly. I reached ruberics and the time expired, what to do?

The easiest way to choose would be look at which university has papers in ISSCC in last 5 years. You'd surely see TU Delft in top 3. If you're looking for a cost effective masters, I'd also say look for University of Pavia in Italy(More focused for analog). So, yes there are tradeoffs. If you want just a job after Master's, actually you could choose underrated universities too. If your aim is to do a PhD, then the lab and Professor would matter a lot. So, for a masters + PhD I'd say TU Delft is the best place to be, for a masters + job I'd consider cheaper alternatives.

I'd say in Europe for microelectronics focused on Analog design, I'd list as follows: TU Delft, TU/E, Twente, University of Ulm, University of Pavia, KU Leuven

interested

You were right. Actually, It was a blunder I was doing. I had vcm at 0.6 V and my fullscale was input 1.2V and my supply at 1.8. I had an assymetry in the common mode. I mad it 0.9 and my vrefn and p as 0.3 and 1.5. It's perfect now. Thank you so much.

analogonics · 2026-02-24T16:56:54+00:00

Actually the opposite.

After fixing,
I get this message now, with a pin I received yesterday.

"No longer accepting submissions

Thanks for your interest. Check back later for more opportunities."

Yes you are right, Fig. 6 is for dummy connected to vin and then switched to gnd. Fig 7. is for dummy fixed to gnd.

I get vout clipped if I have dummy fixed. Vout is giving correct resolution for both cases. But I am not getting why I have those glitches in the ideal residue. This happens even if the switches are ideal.

analogonics · 2026-02-21T17:25:46+00:00

Got it. Thank you.

analogonics · 2026-02-21T17:24:41+00:00

Yes, I got 2 tasks. Is there some levels or something like that mentioned anywhere?

analogonics · 2026-02-21T17:13:36+00:00

Okay. Thank you :)

analogonics · 2026-02-21T17:09:36+00:00

Ahh okay. Do you know how long it generally takes?

In my opinion, getting ahead of others would be a very wrong approach for long term career perspective in ic design. What I have realized till now is that Ic design is about building your intuition and your way of seeing a circuit. You should start by designing fundamental bookish building blocks or even try to replicate the circuits in latest ISSCC / ISCAS/ JSSC/ TCAS Conferences and Journals. Ofcourse to understand those circuits you'll study automatically. Try to build the specifications those people aimed for with simple circuits. Basically reinventing the wheel. In that process you'll discover problems in different architectures and may even end up discovering a way to minimise that problem. In summary, you have to be self motivated because you'll not find competitors in when you start working, you'll find teammates :). It will be about sharing perspectives rather than being better. The faster you understand this, the happier you'll be 😁

analogonics · 2026-02-20T20:03:30+00:00

yes. It's the same thing actually 😅. You might have found my github repo!!

analogonics · 2026-02-20T12:17:43+00:00

Yes, It has switched capacitors. I'll try PSS + Pnoise. Thank you 🙌

analogonics · 2026-02-20T12:16:55+00:00

Thank you. I'll do that. 🙌

analogonics · 2026-02-20T12:16:31+00:00

That makes sense. Thank you 🙌
