Pressure Sensors Based on Modern Nanotechnologies
Magát, Martin ; Hudec, Lubomír (referee) ; Vlach, Radek (referee) ; Vrba, Radimír (advisor)
This thesis describes utilization of a nanotechnology in new pressure sensors. Detailed analysis of individual principles are carrying on. And simulations and experimental models of sensors are developed. More detailed description is provided for new capacitive pressure sensor, which is manufactured using nanotechnology, including its model and analysis in order to improve its properties. The work deals with the emission pressure sensor which uses the principle of cold emissions, including analysis comparison of the measured values of the emission current from the applied nanotubes field and analysis to improve emissions performance.

Design of output digital part for band-pass sigma-delta modulator
Hort, Marek ; Háze, Jiří (referee) ; Fujcik, Lukáš (advisor)
This work deals with questions connected with design of output digital part of sigma-delta conversion unit - band-pass filter type. It was created model of sigma-delta modulator and model of output digital part of conversion unit via MATLAB SIMULINK. Created design was define by VHDL programming language and was implemented to FPGA. Sigma-delta modulator band-pass filter type is part of BANDPASS MODULATOR chip which was designed at Department of microelectronics, University of technology Brno, and witch is designed for measuring of capacity of pressure sensors. There were made PCB for testing of behaviour of output digital part and BPM.
