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 ¥Ä¥Ò 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. |
