  • Incremental converters provide a solution for such measurement applications, as they retain most of the advantages of conventional ${\Delta}{\Sigma}$ converters, and yet they are capable of offset-free and accurate conversion. Most of the previous research on incremental converters was for single-channel and dc signal applications, where they can perform extremely accurate data conversion with more than 20-bit resolution. In this paper, a design technique for implementing multi-channel incremental data converters to convert narrow bandwidth ac signals is discussed. It incorporates the operation principle, topology, and digital decimation filter design. The theoretical results are verified by simulation results.

  • Analog-to-digital converters(ADCs) used in instrumentation and measurements often require high absolute accuracy, including excellent linearity and negligible dc offset. Incremental(integrating) data converters(IDCs) provide a solution for such measurement applications, as they retain most of the advantages of conventional $\Delta{\Sigma}$ converters, and yet they are capable of offset-free and accurate conversion. In this paper, a design technique for implementing multiplexed incremental data converters to convert narrow bandwidth AC signals over multi-channel is discussed. It incorporates the operation principle, topology, and digital decimation filter design. The theoretical results are verified by simulation results.

In this paper, a design technique for implementing multiplexed incremental data converters to convert narrow bandwidth ac signals is discussed. A design methodology to optimize the signal-to-quantization+thermal noise ratio of multiplexed IDC is presented. It incorporates the operation principle, topology, and digital decimation filter design. The theoretical results are verified by simulation results.
