I have also pasted the image which is given on his book at page # 321.
He has used some software for behavioral simulations which must yield at least the signal swings of the integrators.
First, you have to scale coeffients according to reference voltage fullscale(VFS=25mV, in this example), permissible output fullscale voltage of integrator(500mV, in this example) and sampling frequency(fs=6.5MHz, in this example).
You can do this task by using "scaleABCD()" of Richards Schreir's MATLAB Toolbox(delsig).
However you have to relay on state conversion matrix S, since there is excess loop delay compensation path in this example.
S ; The diagonal scaling matrix
ABCDs = [S*A*Sinv, S*B; C*Sinv, D];
Which software should i use...MATLAB???
After getting scaled coefficients, you have to map them to R, C and Idac values.
After getting R, C and Idac values, you have to use Spice Type simulator such as Spectre, Hspice, eldo, etc, with Verilog-A.
Simulink modeling is not appropriate since both voltage and current are involved in this example.
There is a another caution for this example.
Quantizer is 1bit for this example.
So summation before quantizer using "c2" and "a3" is irregular.
