Hello,
I want to design 2-2 cascade delta sigma modulator for 2 mhz signal bandwidth, i must sum the two outputs given by the two stages, i use ORCAD PSPICE for similation, i need to implement H(z) =z^-1 which is a delay unit, i don't know the structure of this function using MOS transistors and how i implement it.
Please help me
