Integrated circuit design (II)
Most popular ΣΔ modulator architectures incorporate a simple comparator as a quantizer [Cand92], which ensures that the re-conversion to the analog plane is perfectly linear. The drawback of such gross conversion, which on the other hand provides very robust operation, is the large quantization noise, whose effect can be attenuated only by increasing the oversampling ratio.
