abstract={Along with the trend to reduce the power consumption of mobile devices, interface circuits such as analog-to-digital converters (ADCs) should also be designed to operate reliably at low supply voltages without compromising production yield. We present a high-fidelity audio {{$\Sigma$}}A ADC suitable for lowvoltage mobile applications, based on a new multi-bit quantizer. Its effective resolution is increased economically by augmenting an internal low-resolution quantizer with the proposed multi-rate noise-shaping technique. Fabricated in a 0.13-$\mu$m CMOS technology, our ADC uses 3.5 mW at 1.2 V, and achieved an A-weighted DR of 108.9 dB and a peak signal-to-noise and distortion ratio of 101.4 dB.},
abstract={n this work we present the design and implementa-tion of a decimationfilter for an audio range -modulator. Thearchitecture is based on a dual wordlength multiply-accumulate(MAC) unit to handle the reduced wordlength of the input.Each stage is composed of FIRfilters which are mapped to theMAC unit. The design trade-offs and decisions for co-design ofarchitecture andfilters are discussed},
