Improved Sigma Delta Modualtor Based On LMS Algorithm
LMS 알고리즘을 이용한 Sigma Delta Modulator
Abstract
This paper proposes a new sigma delta modulator structure based on a LMS(Least Mean Square) algorithm that minimizes the quantization noise. The proposed architecture provides 40dB SNR improvement and 35dB wider dynamic range over conventional sigma delta modulation. The proposed architecture provides superior performance especially when the input signal is small.
