how to take 24 bit discrete signal for cmos design of 24 bit digital sigma delta modulator in electric software

Don't really understand. Do you mean you want a 24-bit (16.777 million) step analog signal to test a 24-bit sigma delta modulator?

digital sigma delta modulator in DAC is digital block i want 24 bit digital test signal means single sample is of 24 bit but i dont understand how to take in cmos design so plz help me.

Does that mean you want to build a custom integrated circuit to generate this 24-bit test signal? If so, that's a very complex task that even an expert designer would have a problem doing.

i want discrete signal source of 24 bit in electric vlsi design system software but i dont get how to take bcoz i want discrete time and discrete amplitude sin signal to my circuit can we take in circuit design?
