    CIC decimation function: integrator, downsample, comb filter

    CIC decimation integrator is very easy implement.you can let ouput value is saved in a delay-register,than add it to input now

    Anyone use MATLAB in VLSI designing

    where do we use matlab yes,but i just use matlab to simulate the whole system.

    How to design Sigma Delta ADC?

    51 sigm delta SD ADC's digital part is so hard to design, it wastes me about two months. someone else have some project to share, thank you so much!

    Problem with noise in Sigma delta ADC

    Noise in Sigma delta ADC analog DSM structure is more simple than others, i think your structure is all right. but some details in your design perhans is not good considered.

    Documents about ADC requirement in Digital Communication

    ADC requirement you can download some paper about these ADC's design. perhaps they are not in detail.

    If there are two negative feedback in one circuit

    agree with JPR, my viewpoint is this circuit is not simple feedback circuit. I have a question:since you think it's a feedback circuit, where is the output point.

    How to choose sigma-delta 1BIT DAC's voltage reference?

    i am a system engineer, but recently i am very interested in ADC's implemention. i have two question: sigma-delta DAC proccess is sharing with the 1 bit DAC??? how mach is the voltage reference??

    2nd order sigma-delta opamp criteria

    Re: Sigma delta opamp choise i think i also relate with noise, the amplifer must be LNA. right?
