35μmCMOS technology, the use of IC design and EDA simulation tool, designed a mainly used in electric energy measurement of 16Σ△modulator, the modulator using 5V single power supply, the sampling frequency of 900kHz, Sampling rate for the 256, the input signal bandwidth of 1.

Modeling and simulation of Σ-△ modulator using Verilog-AMS;

A Higher-Order Σ-Δ Modulator with Improved Integrator Structure;

Sliding mode controller for CCM Buck converters based on Σ-Δ modulator

A new voltage-to-frequency converter based on Σ-Δ modulator technology is designed to convert the analog voltage signal to the corresponding frequency output in micro-accelerometer interfaces.

The operation theory of fractional-N synthesizers based on Sigma-Delta modulator,and characters of a Sigma-Delta Fractional-N Synthesizer MAX2150 are introduced.

To improve the simulation accuracy of SIMULINK,a novel inclusive beha vior model of an integrator is proposed that introduces the effects of different circuit nonidealities of a switched-capacitor sigma-delta modulator into SIMULIK simulation.

Then the first-order and the higher order sigma-delta modulators are analyzed,and finally a method for the sigma-delta modulator based on FPGA is proposed.

A monolithic 16-bit Δ-Σ D/A converter was presented,which was comprised of an interpolator,a Δ-Σ modulator and a power-efficient switching(Class D amplifier) output stage.

The Δ-Σ modulator employs a 5~(th)-order 1-bit quantization loop,and a 100 dB in-band SNR was achieved on FPGA platform.

All analysis of quantization noise for single-loop Δ-Σ modulator for the fractional-N frequency synthesizer is based on linearization assumptions.
