Multi Channel Σ ∆ A / D Converter for Integrated Power Meter
نویسنده
چکیده
This paper describes three architectures for multichannel sigma-delta ADC IC design. The proposed solution is aimed for the front-end of a three-phase integrated power meter. The pervious version of the power meter is to be redesigned by substituting six ADCs with two: one for converting currents and another for converting voltages in the three-phase power system. Therefore one pair of analog 3-to-1 multiplexers precedes ADCs. Discussion of advantages and drawbacks of the proposed solutions is illustrated by simulations using ADMS simulator that is a part of Mentor Graphics design kit.

Optimized Pricing Decisions In a Multi-Level Supply Chain With Various Power and Channel Structures: A Game-Theoretic Approach
This article studies the optimization of pricing decisions in a supply chain with different channels under different power structure. Three different channel will be considered here; these include: the decentralized, the semi-integrated, and the integrated channel. There are two types of power balance structures for both the decentralized and the semi-integrated channels. The first type is a le...
متن کاملA Delta-Sigma beamformer with integrated apodization
This paper presents a new design of a discrete time Delta-Sigma (∆Σ) oversampled ultrasound beamformer which integrates individual channel apodization by means of variable feedback voltage in the Delta-Sigma analog to digital (A/D) converters. The output bit-width of each oversampled A/D converter remains the same as in an unmodified one. The outputs of all receiving channels are delayed and su...
