Webopt A ﬂag used to request optimized NTF zeros. opt=0puts all NTF zeros at band-center. opt=1optimizes the NTF zeros according to the high-OSR limit. opt=2puts at least one zero at band-center, but optimizes the rest. opt=3uses the Optimization toolbox to optimize the zeros. H_inf The maximum out-of-band gain of the NTF. Lee’s rule states that Websince a decrease of maximum out-of-band gain often impacts the in-band attenuation. Because of the similarity to delta-sigma converters, it is possible to use existing design techniques to design the NTF of NS-SARs. The zeros can thus be placed at DC, or optionally at other locations inside the signal band, for instance the optimal ones ...

Web5 apr. 2012 · To get the desired NTFeff ( z ), either the filter coefficients ( K) need to be further tuned or the DC gain and the unity-gain frequency ( fun) of the opamp must be sufficiently large. The latter will result in an increase in the modulator power consumption [ … WebNTF out-of-band gain also increases. The highest out-of-band gain possible for the 6-th order NTF does not compensate the higher order of an 8-th order NTF in terms of SNDR. This is a general observation. Finally, as the number of fractional bits increases, there is no signiﬁcant impact on the maximum possible NTF out-of-band gain. The ...
