In the information age, data transmission system must have a wider data bandwidth and a higher transferring speed. With the development of technology, process dimension is getting smaller, and the supply voltage is becoming lower. But some imperfect factors come out at the same time, skew, crosstalk for example. The common parallel I/O interface circuit,because

Pipeline transport as a safe, economic mode of transport, are widely used in China’s natural gas, oil and other energy transport. Because of long time of media corrosion and wear, pipelines can be damaged in a certain degrees, even may occur a major spill. Besides, the pipeline transportation security relations with the country’s economic and
