Hello,

I am trying to model a 5th order CT Sigma delta modulator in VerilogA, Are there any simple way to implement the transfer function that just derived from simulink as a verilogA model?
I mean H(S) directly as a verilogA model?
 

I am Modeling the 5th order CT SD with feedforward architecture, I couldn't find a similar model in cadence libararies so I implemented my model. However I am not sure how accurate it is

I used Sum, loopfilter laplace_nd() of the transfer function I got from matlab and then ADC and DAC.
