The Design of Multi Bit Quantizer Sigma-Delta Modulator Analog to Digital Converter
Abstract: The paper introduces the principle of sigma-delta ADC modulator with high accuracy and the applied over sampling technique, noise shaping technique and multi-bit quantizer technique. and it makes the behavior level verification for this scheme by Simulink tool in MATLAB. The simulation result Shows that multi-bit quantizer modulator can get very high SNR.
Keywords: Sigma-delta ADC, modulator, over sampling, noise shaping, multi-bit quantization
