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.pdfWe 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).
