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...

A 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...

Charge-pump based switched-capacitor integrator for DS modulators

A low power switched-capacitor (SC) integrator based on a capacitive charge-pump (CP) is proposed. The CP integrator circuit consumes approximately a quarter of the power of a conventional SC integrator while maintaining the same thermal noise performance. Power consumption of the CP integrator is analysed and compared with a conventional parasitic-insensitive integrator. Simulation results ver...

Modeling Band-pass Sigma-delta Modulators in Simulink

In this paper we present a complete set of behavioral SIMULINK models for the simulation of switched-capacitor band-pass sigma-delta (BP ΣΔ ) modulators. The models include most of the non-idealities which affect the performance of these circuits, such as sampling jitter, kT/C noise and operational amplifier parameters (noise, finite gain, finite bandwidth, slew-rate and saturation voltages). W...

Applying POWERSYS and SIMULINK to Modeling Switched Reluctance Motor

Although PSPICE is a powerful tool to simulate the circuits, it is a tough job to simulate the electromagnetic behavior of a converter-fed motor drive, particularly the switched reluctance motor (SRM) with many nonlinearities in its constituted components. Therefore, a simulation environment of the SRM drive combining the features of POWERSYS and SIMULINK is developed in this paper. In the esta...
