The SI and EMI analysis and pre-design of the sensor

The sensor is a multi-board system composed of backboard and other plugging boards. It is a crucial problem that how to assure the signal integrity (SI) for such a complex system. In this paper, we mainly discuss the various signal integrity plots of critical signals in digital circuit board and EMC problems in the multi-board sensor system. The SI and EMC conditions can be improved with the help of the simulations and analysis for the sensor system.
