Design of the voltage controlled oscillator
Richter, Vladimír ; Pavlík, Michal (referee) ; Háze, Jiří (advisor)
This bachelor thesis deals with the issues of voltage controlled oscillators. It analyses their current state and provides the examples of them. It also describes phase locked loop stages and the usage of voltage controlled oscillators in phase locked loops. The main aim of this thesis is to design a voltage controlled oscillator and use it to realize the important simulations.

Interface for plethysmographic sensor
Špánik, Šimon ; Barcík, Peter (referee) ; Kolka, Zdeněk (advisor)
The bachelor's thesis deals with the topic of photoplethysmography and the signal produced by the photoplethysmographic sensor. The goal is to design a laboratory device that would serve as an interface between a photoplethysmographic sensor and a computer. The work describes the anatomy and function of the human heart, the principle of photoplethysmography, and the properties of the sensor in terms of input and output signals. Also presented here is the method of powering and filtering the relevant circuits in the form of an additional printed circuit board for a standard Arduino microprocessor module, which is powered by USB. Furthermore, in the work, it is possible to find a solution to the influence of unwanted signals using filter analog circuits and the minimization of the measured signal's own noise, which prevents the signal from continuous values to discrete time and subsequent storage using a computer application on the data storage for subsequent signal processing.

Adaptive System Design in a Reconfigurable Platform Using the Embedded Analog-to-Digital Converter
Zamba, Martin ; Růžička, Richard (referee) ; Dobai, Roland (advisor)
This thesis has its main subject pointed on possibilities of exploiting reconfigurable digital systems on FPGA basis in mixed signal applications. Description of reconfigurable and adaptive systems in general and summary of known architectures is presented in first part of this work. Next, possibilities of exploiting configurability of FPGAs in conjunction with XADC digital to analog converter are examined. These converters are provided in 7-series FPGAs and Zynq-7000 systems from Xilinx. Concept of exploiting XADC for inductance measurements is presented as alternative to existing solution - LDC1000 integrated circuit provided by Texas Instruments. Such system utilizing FPGA and XADC would come with a lot of benefits: better system integration, better signal processing options, possibility of constructing adaptive system with numerous sensory elements and last but not least, lower system cost. Advantages and disadvantages of such approach are analyzed in the very final part of this work and possible options for extension of this work are presented.
