| Abstract: | The most accurate analogue-to-digital converter design presently known integrates the input voltage and employs the dual-slope principle for digitisation. However, without additional external components it is only suitable for unipolar operation, and continuous integrations are not possible, because some time is needed for the conversion process after every integration. An extended design, overcoming these two shortcomings, is given in the present paper. Furthermore, its application in multichannel measuring systems is discussed, using star-shaped and bus connections to the controlling unit, with only a single transmission line each. |
