The bandpass delta-sigma A/D converters are placed into the Weaver architecture in this paper. One reason for this architecture is that using the noise shaping and oversampling method can minimize the quantization noise; the other is that this architecture increases the utilization of digital circuits and eliminates the passive RF image rejection filter. More programmability and flexibility can be achieved; that is, this architecture can be applied to different receivers
