A Partial Tree Vector Quantizer Dynamic Element Matching Technique For Audio Delta-Sigma Converters |
Abstract | ||
---|---|---|
Multi-bit Delta-Sigma modulators are widely used in performing accurate, low-power, and low cost analogue-to-digital conversion (ADC). One of its major limits is the internal feedback digital-to-analogue converter (DAC) non-linearity. It generates unwanted tones and noise in the band of interest, which makes impossible to achieve the signal quality required in audio products. Authors have overcome this difficulty by designing mismatch-shaping techniques, also called Dynamic Element Matching (DEM). We propose in this paper a new vector-based DEM that we have added to a 4(th) order continuous-time ADC. It achieves good audio performances for a reasonable gate count. |
