The Intrinsix Sigma-Delta Stereo ADCs for High Performance Audio (SD-ADC-HPA) are part of the larger offering of Sigma-Delta IP available from Intrinsix.
The family of SD-ADC-HPA is generated utilizing proprietary, patent-pending techniques within the Intrinsix SDM Refinery toolset. A design methodology that is geared towards a digital CMOS process helps reduce cost, die size and power consumption. A high Signal to Noise Ratio (SNR) is achieved by pushing the frequency of the quantization noise outside the band of interest. The challenge in Sigma-Delta ADC design is the "shaping" of this noise, which is characterized by the Noise Transfer Function (NTF), and the design of efficient filters to attenuate the noise. The SDM Refinery automates this process: The engineer specifies an Over-Sampling Ratio (OSR), quantization levels, order of complexity and SDM Refinery creates the desired ADC.
