Binary network for a according to the principle of successive approximation analog-digital converter operating with redundant weight

摘要

Binary network for digital-to-analog conversion for a according to the principle of the successive approximation, analog-digital converter operating with:– N binary weights (g1 to g8) and– in addition at least one redundant binary weight (g5''),each weight in each case one point of a formed within the scope of the approximation corresponds to the redundant binary code and the weight value of the redundant weight (g5 '') of the weight value of the m most significant weight (g5) corresponds to the n binary weights,characterized in thatduring the scanning of the input signal (v to be reacted by the analog-digital converter_in'') the weights from the most significant weight (g8) to the m most significant weight (g5), as well as the redundant weight (g5 '') with the input signal (v_in'') are electrically conductively connected to.
