In traditional temperature measurement system design, often using simulation technology to carry on the design, it will inevitably encounter such as lead error compensation, multi-point measurement error switch and signal conditioning circuit error problem; and a part of a deal with them improperly may cause a decline in the performance of the whole system.?With the rapid development of modern science and technology, especially the development of large-scale integrated circuit design technology, miniaturiza
