Abstract: At the moment determining of the pulse wave main parameters using a piezo sensor is performing using the RC adjustments in the circuit. With the increasing adaptation of the virtual instrumentation it is possible to reduce the RC complexity. The purpose of this work was to determine the piezo-electric actuator transfer function according to the signal of the air pressure sensor using virtual instruments. In this works it was created a virtual piezo-electric sensor transfer function measurement model which proved that in order to change the sensor frequency amplitude we do not need to use electronics components.

Abstract: In this paper, we introduce a chip ID generation circuit, which uses process variations, that appear during the physical execution of an FPGA. In [1] Gassend et al. introduced for the first time the ROs digital circuit with the aim of emphasizing the uncontrollable effect of silicon process variations at the delay of the digital component interconnection. After that, different constructions based on process variations start to appear. The digital circuit analyzed is a modification of the latch based circuit with the scope to minimizing the hardware resource usage and to fit an FPGA implementation. We also introduce a new statistic assessment method based on Kolmogorov-Smirnov test for the inter-distance and the intra-distance analysis. The chip ID generation circuit could produce FPGA secret keys that deal with the security issues such as: cloning, overproducing or stealing the implemented applications on FPGA.
