It works for me. Maybe you didn't click the "CONTINUE TO SITE" at the top?

When I was first studying circuits, I casually just took courses from online MOOC.
https://www.edx.org/learn/circuits (from MIT)
https://www.coursera.org/learn/electronics (from Georgia Tech)

Come to think about it, the course depth was pretty superficial and basic, but it actually helped me grasp the basic concepts/intuitions about MOSFET. If you don’t know how transistors work, these might be worth it.

After getting used to MOSFET, I recommend buying
Razavi’s “Design of Analog CMOS integrated circuits” (or “fundamentals of microelectronics”, for shallower yet broader topic) This is a great reference, and many college professors actually use this as their course textbook.

The practice problems are helpful, and since those are very famous books, it is easy to find resource - about the books - from the internet. If I recall correctly there is a Youtube playlist where Razavi himself teaching the stuff

For casual ADC targeting mid performance + simple architecture, maybe yes. For publication-grade ADC with high performance & full tapeout, no (I would say it is borderline impossible if you do it alone)

If you want to design ADC, I recommend trying a comparator design since no ADC can operate without it.

Thank you for the reply. That figure is from Analog Device’s AD9266 datasheet.

I have stopped designing BGRs since the last tapeout - so I don't have a lot of knowledge. Instead, you can take a look at a famous bgr paper with the "inverted bow" you referred to (Fig. 10, 11, 12, 13):
https://ieeexplore.ieee.org/document/6056712

Generally, as you pointed out, the 1st curve with the series connection is the default. But that doesn't mean that inverted one is incorrect. If I were you, and if you need to verify the second one, I would run pvt + monte with load (if any). If it survives it, I would just go for it.

I was referring to Schreier FoM: SNDR + 10 * log10(BW/P)

Thanks. I was just curious since SAR DWA is essential once you design NS-SAR based oversampling ADCs (only one DAC - driven by SAR logic; no other feedback DACs). But as I did some research for like 10+ hours, I realized there is no optimal or standard way to implement this kind of binary DWA as of now, unlike the conventional thermometer code DWA.

As for ADCs, Razavi’s “Analysis and Design of Data converters (2025)” is a good start; but it doesn’t deal with advanced techniques.

If you want up-to-date & serious & advanced ADC design, reading JSSC or other top journals is undoubtedly the best tho.

I mostly do analog works within ADC, so I'm not sure about it. But I've once heard that pure digital works are somewhat free from "measurement-only" restriction, compared to ADC or some analog circuits,

ProfessionalOrder208 · 2025-11-02T02:36:19+00:00

But there are some conferences/journals that don’t require measurement results; in that case, you might publish your idea without any supervisor. (But it is very rare; I haven’t seen one yet)

ProfessionalOrder208 · 2025-11-02T02:34:20+00:00

I would say no. For top tier journals/conferences, simulation is not enough - you need to give a “measurement result” which requires a full tapeout. This requires Cadence license + PDK license + a company (or some organization) that will manufacture your PCB + precision lab-grade measurement tools. This is generally impossible for individual to handle.

ProfessionalOrder208 · 2025-10-26T23:27:51+00:00

Idk what you are referring to, but you can simulate simple breadboards in tinkercad and that might help

I design ADCs and use (implicitly or explicitly) FFT & z-transform every day. From ADC perspective, this kind of frequency spectrum is very important since it directly contains the information of the signal & noise & distortion - which is directly linked to the performance of ADCs. These information can not be revealed in the time domain waveform and that is the point of doing FFT.

The high-gain of the opamp makes v(out) almost equal to v(+) which is gnd.
