sigma delta adc design

Hello, everyone, I'm a graduate student in China, it's very happy to join in you. I want to do some research of Sigma Delta ADC? Can you give me some advices? thank you very much. Excuse for my poor English.
 

delta sigma adc design

Sigma-delta ADC is included two parts, one for adc and the other oof sigma-delta. Sometime besides of sigma-delta, over-sample is added. Before you do sigma-delta adc design you need do system level design to determine how may order of you need. Based on the order, then you design the system fuction, basiscally signal flow or modultor.

sigma delta modulator design

Well, thank you very much. I also have a question, as we all know that, the most circuit is digital, can I design this part by HDL? which is better, verilog or VHDL?

unfortunately most of the sigma-delta ADC is ANALOG :))) Sigma-Delta ADC has 2 parts: modulator (analog) and decimation filter (digital). Usually modulator is the most difficult part of the design.

I would recommend you to read some basic overview about ADCs and sigma-delta ADCs. IMHO, the appropriate chapters from Davis & Martin would be ok..

P.S. Comparing VHDL and Verilog - they are similar, its your choice what to choose.. Look which similator you have (especially if you wantr to use analog or mixed signal extensions like Verilog-A/Verilog-AMS or VHDL-AMS) for behavioral simulations.

excuse me , how to find the book you just mentioned?
Thanks!

delta sigma design

for analog part of sigma delta adc ( sigmadelta modulator), system define is very important, so behavior simulation must be done before transistor level simulation. I think it is good for you to refer some basic books or papers to understand transfer function, then add more and more nonideality to behavior model, at last there will be only opamp and comparator to design

sigma delta adc

Read David and Martin's CMOS Analog IC Design,then find some classic references on IEEEexplore to get further understanding.

It's so kind of all of you. Now I'm learning DSP and verilog by myself, are they useful? And what other should I learn? Please tell me ,thank you very much.
 

delta-sigma adc designs

What is your major?If IC design, I suggest you'd better learn Verilog/A for digital logic synthesis or analog/mixed-signal behavior modeling.
 

verilog-ams sigma delta modulator pdf

I major in IC design, what you mentioned is verilog and verilog-A, is it right?
 

sigma delta adc modulator

Verilog is most popular tool for logic synthesis (ASIC),Verilog-A for analog,verilog-AMS for mixed-signal.
U need to understand Verilog first.However, it will take a long time to master both the language and analog IC design skills.

design of a adc

hi,
Before you start your circuit design, I suggest you should learn more about the
sigma-delta ADC spec, including the SNR, the THD+N and so on.
the system view is more difficuilt than circuit design.
also you can easily find reference about it.
Brs,

digital part of the sigma delta adc

To gevy,
Do you have that sigma-delta ADC book ? Can upload to here ? I'm also interested in sigma-delta ADC circuit design , but I did not know how to design decimation filter , anyone one has some design example regarding how to implement a digital filter using Verilog ?
 

fpga sigma delta adc

By the way , I think to design a sigma-delta ADC , the system simulation should be done by some math. tools such as matlab. I can not found the matlab files regarding the sigma-delta ADC circuit design , anyone knows where can I found such kind of M-file ?
 

delta-sigma adc design

It's very lucky, I have some. It is about 2-order, 3-order, 4 order model, noise model, SNR caculation and so on, I'm not very clear, hope it useful to you. :)
