Sigma-Delta Modulator Simulation and Analysis Using MatLab
In addition to compatibility with VLSI technology, sigma-delta converters provide high level of reliability and functionality and reduced chip cost. Those characteristics are commonly required in the today wireless communication environment. The objective of this paper is to simulate and analyze the sigma-delta technology which proposed for the implementation in the low-digital-bandwidth voice ...
متن کاملAnalysis and simulation of a cascaded delta delta–sigma modulator
This paper analyses and simulates a delta delta–sigma modulator, the cascade combination of a delta modulator and a delta–sigma modulator. Using prediction, the delta modulator reduces the dynamic range of a signal prior to quantisation. Using noise shaping, the delta–sigma modulator cancels the error of the delta modulator. Performance is evaluated with input signals from a random noise proces...
متن کاملSystem-Level Simulation for Continuous-Time Delta-Sigma Modulator in MATLAB SIMULINK
This paper discusses a set of techniques for system-level simulation of continuous-time delta-sigma modulators (CT ∆∑M). In a top-down design flow, system-level simulation is an important part. Done accurately and correctly, system-level simulation can help predict when the circuit operates best and also when and where it fails. The building blocks in a CT ∆∑M and how the non-idealities with ea...

This paper presents a circuit including a high-pass Σ∆ modulator implemented in CMOS process and a timeinterleaved high-pass Σ∆ analog to digital converter.
متن کاملStability and Performance Analysis of an Adaptive Sigma–Delta Modulator
This work develops an adaptive sigma–delta modulator that is based on adapting the quantizer step-size using estimates of the quantizer input rather than the modulator input. The adaptive modulator with a first-order noise shaping filter is shown to be bounded-input bounded-output stable. Moreover, an analytical expression for the signal-to-noise ratio is derived, and it is shown to be independ...
