Knowing the phase jitter is helpful for improving the design quality of a GHz clocking system. In this paper, we present how to design a low-power and low-cost built-in jitter measurement (BIJM) circuit in 28 nm CMOS for monitoring the on-chip clock jitter in DDR4-2133. The implementation and measurement results show that the proposed BIJM achieves a 77% power reduction and a 7% area reduction compared...
Forewarning to avoid potential traffic accidents is of great importance for Intelligent Transportation Systems (ITS). Under pedestrian and vehicle mixed traffic conditions like urban road intersections, traffic monitoring and forewarning have especially important values. Therefore in this paper a novel urban traffic information analysis and forewarning system is presented. Our system contains modules...
Since its parameters can not been test about the certain gas turbo-generator set in local rapidly after repairing, a monitoring and fault diagnosis system based on IPC is designed in this paper. The system adopts advanced measuring technology based on PCI bus, intelligent appearance and VI technology and can check voltage, electric current, power and temperature of key parts on-line about the set...
