    delta sigma simulink

    I am designing a Delta sigma ADC, so i need some guidence for designing it in simulink, and i have to do circuit design as well in 0.18u technology in cadence. guide me please. Thanks in advance!

    Re: design of Delta Sigma in simulink

    im designing discrete time DSM. i know circuit design but prob. with simulink, how do we get noise plots in simulink as others get. can you please provide me a complete example of 2nd order low pass SDM in simulink with gain parameters. when i did ,it was going way hign in magnitude after the 2nd integrator. thanks for your reply.

    Re: design of Delta Sigma in simulink

    here is the screen shot of 2nd order SD Modulator and its psd output. i would like to know how to get db Vs F plot.
    Sin input amp 0.8,
    f=10hz,
    sample time of delay elements 0.001
    sample time of power spectral density block 0.005

    the block diagram and psd plot is attached.

    please help me get through this.
    Thanks!

    design of Delta Sigma in simulink

    helloo
    may i ask a question about this block diagram please.
    first i'd like to design a mash 111 SDM, then i'm asking weather these blocks are a matlab function,. ... u designed it from scratch inside the simulink or these blocks are the normal simulink blocks.
    2nd i'll be much thankful if u uploaded a block digram of a mash 111 SDM. or any other suggestions i'll appreciate
    thank u very much :)
