Matlab codes are provided for min-max optimization for loop-filter design in delta-sigma modulators.
The MATLAB codes are based on our recent paper:
M. Nagahara and Y. Yamamoto,
Frequency-Domain Min-Max Optimization of Noise-Shaping Delta-Sigma Modulators,
to appear in IEEE Trans. SP, 2012.
A draft can be down-loaded via:
http://www-ics.acs.i.kyoto-u.ac.jp/~nagahara/ds/manuscript.pdf

We give two matlab codes:
[ntf,R]=NTF_MINMAX(order,OSR,Hinf,f0,zf)
[ntf,R]=NTF_MINMAX_MB(order,OSR,Hinf,f,zf)
By these codes, one can obtain lowpass/bandpass (by NTF_MINMAX) and multi-band (by NTF_MINMAX_MB) filters for noise-shaping delta-sigma modulators that minimize the maximum magnitude of the noise transfer function (NTF)
in fixed frequency band(s).
