“…The second class contains the works aiming to predict or simulate the performance of different types of ADCs based on their infrastructure characteristics and features, usually in MATLAB Simulink or Spice. [2], [3], [6]- [10], [12]- [14] are some examples for this category. Generally speaking, the first category has attracted more interest than the other over the past decade.…”

Analog-to-digital converters (ADC) are one the most fundamental and crucial parts of an electronic device which needs to convert analog inputs into the digital format. Nowadays, you can find some type of ADCs in almost every communication device. Consequently, simulating an ADC plays a challenging and very fundamental role while aiming to simulate real-world instruments and designed systems. Despite the fundamental significance of this task, a general simulation model for typical non-ideal ADCs have not been presented yet. In this paper, we consider the most important non-ideality parameters of a typical ADC and initiate simulation models in the Simulink environment of MATLAB, as the most versatile widely-used simulation software for engineering tasks. For this purpose, we first reconsider the non-ideality parameters of a typical ADC from general perspective, aiming to bring a unified view in hand. Afterwards, the potential models for the non-ideality parameters are initiated separately, and then, are combined together to make the whole model. By creating a MATLAB Block of the whole general-topology model at the end, and defining the non-ideality parameters as variable inputs, we simulate the behavior of a typical ADC using practical non-ideality parameters data, and compare with an ideal ADC. This additionally enables a user interface for quick input of non-ideality parameters of any practical ADC for future clients. Despite the pure generality of the model, simulation results demonstrate acceptable outcomes proving the applicability of this model in wide range of engineering simulation tasks, and an appreciable step towards higher precision general simulations of typical ADCs.

“…(Bernhard, 1988) studded the oversampled analog-to-digital converter architectures and proposed a second-order Σ-ΔM circuit which offers a means of exchanging resolution in time for that in amplitude so as to avoid the difficulty of implementing complex precision analog circuits. In Jaykar (2011), the authors proposed a set of models which takes into account SC Σ-ΔM nonidealities, such as sampling jitter since switching circuitry is included, kT/C noise, and operational amplifier parameters (noise, finite dc gain, finite bandwidth, slew-rate and saturation voltages). Each nonideality is modeled mathematically and their behavior is verified using different analysis in MatLAB Simulink.…”

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 communication. The results of simulation show the superior performance of the converter compared to the performance of more conventional implementations, such as the delta converters. Particularly, this paper is focused on simulation and comparison between sigma-delta and delta converters in terms of varying signal to noise ratio, distortion ratio and sampling structure.
