Enhanced Generic Architecture for Safety Increase of True Random Number Generators

Conventionally used generic architecture of true random number generators does not allow testing of random numbers during their generation. This paper introduces an extension of the conventionally used generic architecture and describes mechanisms that can be implemented in new blocks and en...

Mechanical and electrical properties of evaporated thin layers

The study deals with the vacuum evaporation technique of thin layers, considering different process parameters and their influence on electrical properties. Parameters, such as temperature, different substrate types, substrate vibrations, etc., are considered. The effects of the process parameters on&...

Comparison of Waffle and standard gate pattern base on specific on-resistance

The main goal of this work is to compare the different Waffle MOS structures as function between main dimensions and channel resistance (specific on-resistance). Even if Waffle MOS structure is so general that it is independent on dedicated CMOS process in fact constrains coming&#x...

Charge Redistribution and Restoring voltage of Supercapacitors

Electric charge in supercapacitor is stored on electrodes as well as inside its electrolyte. Charges on electrodes create Helmholtz double layer which is formed immediately with time constant in the order of seconds, while the storage of charge in electrolyte takes time in the ...

An Accurate Voltage Reference For Automotive Applications

This article compares different topologies of simple accurate bandgap voltage references. The proposed topologies are the Brokaw bandgap reference and CMOS bandgap reference in two variants with NPN bipolar core and with PNP bipolar core. For automotive applications with wide temperature ran...

Statistical characteristics of electromagnetic emission signals of mechanical loaded composite samples

This article presents study of statistical characteristics of EME signals. The theoretical part contains a description of stochastic nature of electromagnetic emission. We describe the measuring system, the sequence of the experiment, statistical characteristics (probability density function, mean quantity...

Scanning Probe Microscopy in Technology of Solar Cells Production

This article deals with implementation of Scanning Probe Microscopy (SPM) techniques to the characterization of crystalline silicon solar cells. Atomic Force Microscopy (AFM) is used for the characterization of solar cells texture, because it allows three dimensional imaging of surface structure&...
