Moroz A. Regulated power supply filters for microcontrollers with supply current masking

The dissertation is devoted to the development of theory of regulated power supply filters for microcontroller and microprocessor systems with power supply current masking by using wavelet and spectral analysis in polar coordinates, as well as interpolation and integral factor in polar coordinates. A comparative analysis of existing methods of information signals disguising in microprocessor systems, including protection against power supply analysis, including their characteristics was conducted in order to identify their weaknesses and ways of improvement. Theory for building algorithm of discrete wavelet analysis and spectral analysis in polar coordinates to develop commands classification in real time was developed. Theory for constructing schemes and algorithms of regulated power supply filters with information signals masking in current consumption is created. Efficiency of proposed regulated microcontroller semiconductor power supply filters, as well as developed algorithms and devices was researched.
