In this paper, a model for MEMS capacitive microphone is presented for integrated circuits.  The microphone has a diaphragm thickness of 1 μm, 0.5 × 0.5 mm2 dimension, and an air gap of 1.0 μm. Using the analytical and simulation results, the important features of MEMS capacitive microphone such as pull-in voltage and sensitivity are obtained 3.8v and 6.916 mV/Pa, respectively while there is no...

A newly developed optical method for noninvasively measuring the switching activity of operating CMOS integrated circuit chips is described. The method, denoted as picosecond imaging circuit analysis (PICA) can be used to characterize the gate-level performance of such chips and identify the locations and nature of their operational faults. The principles underlying PICA and examples of its use...

Rio de Janeiro’s Integrated Command and Control Center (CICC-RJ ) has already seen duty in several large scale events which happened in town, some planned, others not. CICC-RJ is part of Rio de Janeiro state’s response to the Brazilian national government’s mandate to improve the state’s ability to anticipate and respond coherently to public safety events in the region. Its infrastructure is in...
