Can a second order bandpass sigma delta modulator achieve high signal-to-noise ratio for lowpass inputs [PDF]
, 2008 Institutively, second order SDMs usually achieve lower SNR than high order ones because high order loop filters can achieve better noise shaping characteristics. Moreover, the signal transfer function should be designed to have large values and the noise
