Abstract
This paper presents the implementation and design of adaptive noise cancelling filters using the Delta Sigma Modulator (DSM) ADCs. It has been clearly shown how the process of recursive or pipelined noise shaping based conversion used in ADCs can achieve higher speeds even after employing Oversampling above Nyquist rate with recursive encoding. The various parameters affecting the design and performance of the DSM ADCs employed filter design have been analyzed. Stability considerations of higher order sigma delta modulators have also been analyzed to attain an optimized approach to decide upon the design of the DSM. Variation in the SNR has been shown with changes in Over Sampling Rate.Keywords: Adaptive Filter Design, DSM ADCs, Over Sampling Rate, Signal to Noise Ratio, Dynamic Range, Quantization Noise.
