Behavioral Modeling of Switched-Capacitor Sigma–Delta Modulators
This paper presents a complete set of blocks implemented in the popular MATLAB SIMULINK environment, which allows designers to perform time-domain behavioral simulations of switched-capacitor (SC) sigma–delta ( ) modulators. The proposed set of blocks takes into account most of the SC modulator nonidealities, such as sampling jitter, noise, and operational amplifier parameters (white noise, fin...
متن کاملBehavioral modeling of delta-sigma modulators
This paper presents an overview of DelSi, a MATLAB toolbox developed for the design and simulation of delta–sigma modulators. The DelSi toolbox can synthesize a stable noise-transfer function for complex network structures. The modelling tool consists of two crc programs, sdMod.c, a single stage delta–sigma modulator and firfilt.c, a decimating FIR filter. Cascaded modulators can be constructed...
متن کاملComparator-Based Switched-Capacitor Delta-Sigma Modulation
In order to eliminate the use of operational amplifiers (opamps) in sampled-data systems and thus avoid several delicate tradeoffs involved with their design, a new class of switched-capacitor circuits based on comparators was reported. The novelty of this comparator-based switched-capacitor (CBSC) design method is the detection of a virtual ground condition rather than forcing it through feedb...
متن کاملHigh Frequency Behavioral Modeling of Second-Order Sigma Delta Modulators
Sigma delta modulators (ΣΔMs) form part of the core of today’s mixed-signal designs. They are cornerstone components of oversampled data converters. Such data converters take advantage of digital signal processing techniques and VLSI technology to provide high performance with low sensitivity to analog component imperfections and noisy conditions. The ongoing research on these devices shows the...
متن کاملA SIMULINK-based approach for fast and precise simulation of switched-capacitor, switched-current and continuous-time Sigma-Delta modulators
This paper describes how to extend the capabilities of SIMULINK for the time-domain simulation of ZA modulators implemented by using switched-capacitor, switched-current and continuous-time circuits. considering the most important error mechanisms. The behavioural models of these circuits are incorporated into the SIMULINK environment by using C-language S-function blocks, which leads to a dras...
