designing sigma-delta converters

Does anybody use the Midas for behavour-level simulation of delta-sigma modulator? I think it should be much faster than simulink.

tutorial on delta sigma adc design

upload more theses: the last one was really good.

upload one with sizes, transistor sizes, full schematics.

full design procedures.

Is there any pdf version of the book " understanding delta-sigma data converters"
It is 100 euros here in Belgium.

What is behavioral simulation for Sigma-delta ADC?
Is there any difference between the behavioral simulation and system level simulation?

Good for guys working in company! haha

This topic is very hot!

I am asking a testing problem for DAC , I think ADC is the same.

I am testing DAC using the discrete data obtained from HSPICE simulation. Data frequency is (15/32)*50M and sampling frequency is 50MHz.

However I found that even the data is got from ideal DAC , the FFT plot is not satisfying in matlab with only about 20dB SFDR.

Anyone can tell what is the problem ?

Even with more data points, the situation is the same.

I am using a perl script to generate the ideal DAC output , I am wondering whether the perl script does not have enough accuracy.

I am using 512 sampling points.

verilog delta sigma adc

now i am design a sigma delta adc, and i encounter a problem, when the adc run(in hspice) for several periods the supply voltage of the adc(which is generate with a regulator on chip) will oscillate, then the clock signal will very dirty and the input and output signal of the integrator oscillate too, and the modulaor is destroyed. I don't konw where the oscillation source is ? it that come from the sc cmfb net of opamp ?
hope someone can give some advise!

is there toolbox for sigma-delta in simulink?

To design Sigma Delta, firstly it is needed do design your order and transfer function. After that we need to verify whether ur system is stability or not. Then proceed a cicuit simualtion

design of sigma delta

as for sigma delta, it is a old topic and also new topic. In fact, there is many confusion conclusion and research result. you need with suspicion when you study this topic.
