Continuing scaling of CMOS technology has allowed aggressive pursuant of increased clock rate in DSM chips. The ever shorter clock period has made switching times of different inputs on a logic gate ever closer to each other. The traditional method of static timing analysis assuming single input switching is no longer adequate enough to capture gate level delays accurately. Gate delay models considering...
Three single micromachined fibre optic silicon sensing units are combined to form an impact sensor. The relative signal arrival times are used to localise an impact and the output optical signal varies directly as impact magnitude. 0.5 mJ impact energy is detected and 30 mm impact location accuracy is achieved over a 1.4*1.2 m/sup 3/ area.<<ETX>>
