Patent ID: 7307567

Claim:
A digital-analog converter having: a) an array arrangement having a number of cells between a first and a last cell configured to output at least one quantized analog signal, the cells having a local decoder device configured to receive two row actuation signals and three colunm actuation signals; b) a dynamic element matching (DEM) logic device configured to generate at least one arithmetic sign signal and two digital output data items from digital input data on the basis of a predetermined DEM algorithm in order to determine an initial cell and a final cell in the array arrangement having energy sources which are to be activated, the at least one arithmetic sign signal determining whether cells adjoining the first cell in the array arrangement are activated if the cells to be activated reach the last cell in the array arrangement; and c) a decoder device configured to decode the at least one arithmetic sign signal and two digital output data items from the DEM device into the two row actuation signals and three column actuation signals, which are coupled to the array arrangement for the purpose of activating energy sources for the cells which are to be activated.
