چکیده

This work investigates the commonly used Asynchronous Sigma Delta Modulator which consists of a schmitttrigger and a continuous time loop filter. A detailed analysis is presented to accurately predict the distortion of such modulators. The extracted expressions are compared with simulation results and they illustrate an excellent match. The results are also compared with a previous work by Roza and they show a drastic improvement in accuracy.

Time-Mode Signal Quantization for Use in Sigma-Delta Modulators

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...

Decrease in Hardware Consumption and Quantization Noise of Digital Delta-Sigma Modulators and Implementation by VHDL

A new structure is presented for digital delta-sigma modulator (DDSM). Novel architecture decreases hardware consumption, output quantization noise and spurs in Comparison to previous architectures. In order to reduce the delay, power consumption and increase maximum working frequency, the pipelining technique and the carry skip adder are used. Simulation proposed architecture shows that the qu...

Effect of non-linear settling error on the harmonic distortion of fully-differential switched-current bandpass Sigma-Delta modulators

This paper presents a detailed study of the effect of the non-linear settling on the harmonic distortion of Bandeass ZA Modulators (BP-UMs) realized using Fully Differential (FD) &vlrched-current (SI) circuits. Based on the analysis of building blocks, closed-form expressions are derived for the third-order intermodulation distortion of BP-XAMs due to defective settling, on the one hand, and to...

Performance Scrutiny of Two Control Schemes Based on DSM and HB in Active Power Filter

This paper presents a comparative analysis between two current control strategies, constant source power and generalized Fryze current, used in Active Power Filter (APF) applications having three different modulation methods. The Hysteresis Band (HB) and first-order Delta-Sigma Modulation (DSM) as well as the second-order DSM is applied. The power section of the active power filter is viewed as...

Nonlinearities in Sc Delta-sigma A/d Converters

The effects of using nonlinear low-gain opamps in switchedcapacitor delta-sigma modulators are analyzed. Using unconventional topologies, the state variables are made essentially uncorrelated with the input signal, hence opamp nonlinearity will cause very little harmonic distortion. Nonlinearity errors, whch are uncorrelated with the input, are called non-harmonic distortion. Using a correlated...
