Adaptive Sigma–Delta Modulation With One-Bit Quantization
A method for improving the signal-to-noise ratio (SNR) of sigma–delta modulators with one-bit quantization is presented. The two-level feedback signal of a standard sigma–delta modulator is replaced by a multilevel signal, which is a superposition of two parts. One part ( ) represents a rough estimate of the instantaneous amplitude of the input signal (prediction signal), and the other ( ) is t...
متن کاملThe Design of a Multi-bit Quantization Sigma-delta Modulator
Sigma-delta ACD has two main parts: analog modulator and digital filter, the performance of modulator determines the performance of sigma-delta ADC, so the design of modulator is very important. The paper introduces the principle of sigma-delta AD modulator with high accuracy and the applied over sampling technique, noise shaping technique and multi-bit quantizer technique. Determining the desi...
متن کاملDescription of a 2-Bit Adaptive Sigma-Delta Modulation System with Minimized Idle Tones
A 2-bit adaptive sigma delta modulation system that inherently eliminates the idle tones present in conventional and other adaptive sigma delta systems is described. The system incorporates both memory and look-ahead instantaneous step-size estimations and, as shown by computer simulation results apart from eliminating the unwanted idle tones despite dithering, it offers improved SNR performanc...
متن کاملAn Optimal Family of Exponentially Accurate One-Bit Sigma-Delta Quantization Schemes
Sigma-Delta modulation is a popular method for analog-to-digital conversion of bandlimited signals that employs coarse quantization coupled with oversampling. The standard mathematical model for the error analysis of the method measures the performance of a given scheme by the rate at which the associated reconstruction error decays as a function of the oversampling ratio λ. It was recently sho...
متن کاملAdaptive one-bit quantization for compressed sensing
There have been a number of studies on sparse signal recovery from one-bit quantized measurements. Nevertheless, less attention has been paid to the choice of the quantization thresholds and its impact on the signal recovery performance. In this paper, we examine the problem of quantization in a general framework of one-bit compressed sensing with non-zero quantization thresholds. Our analysis ...
