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...
Several correlated issues of autonomy and simplicity regarding formation control for robots with a self-awareness mechanism in unstructured environments are considered. To achieve autonomy and simplicity, a hybrid scheme is derived for robot maneuvering based on a multibehavioral system. The system holds some self-awareness capabilities ensuring precision and robustness in the presence of internal...
Based on the stress induced void theory, three kinds of narrow-wide two-layer copper interconnection structure with dummy via in M1 were designed and put under different high temperature conditions for test. Under the action of high temperature, influence of dummy vias in lower layer metal (M1) on the failure phenomenon of the interconnect structure was analyzed. The result shows, adding dummy via...
