چکیده
This paper presents a complete set of SIMULINK ® models, which allow exhaustive behavioral simulations of any sigma-delta modulator to be performed. The proposed set of models takes into account most of the sigma-delta modulator non-idealities, such as sampling jitter, kT/C noise and operational amplifier parameters (noise, finite gain, finite bandwidth, slew-rate and saturation voltages). For each model we present a description of the considered effect as well as all of the implementative details. Simulation results on a second-order switched-capacitor sigma-delta modulator demonstrate the validity of the models proposed.

The rapid scaling in modern CMOS technology has motivated the researchers to design new analog-to-digital converter (ADC) architectures that can properly work in lower supply voltage. An exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. This paper is going to review the recent development in t...

متن کاملBehavioral Analysis of Second Order Sigma-Delta Modulator for Low frequency Applications
Switched capacitor (SC) based modulator is prone to various non-idealities; especially at the circuit designing stage where the integrator plays an important role and effects the overall performance of the sigma delta modulator. The non idealities take account of sampling jitter which includes the effect of switching circuitry, sampling noise. Opamp parameter include noise, finite dc gain, fini...
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...
