Graphical user interface for filter design
Tesařík, Jan ; Kledrowetz, Vilém (referee) ; Pristach, Marián (advisor)
This work deals with design of program that allows to generate VHDL description from connection of filters. Its main aim is to create graphical extension on existing program and connect it to VHDL generator. Output from program will be XML file of created connection and generated VHDL description. Design of program was done by using Qt Framework environment and C++ language.

Car Audio Amplifier
Vičar, Ondřej ; Kledrowetz, Vilém (referee) ; Pavlík, Michal (advisor)
Aim of this bachelor´s thesis is design of a four-channel audio amplifier of the power of 4 × 60 W intended for using in cars. The Amplifier is designed with integrated circuits LM3886T and is supplemented by design of a power supply in a form of a voltage converter. The voltage converter is controlled by an integrated circuit SG3525AN and works in push pull topology. All circuits were made and placed in instrument box. On the final device were performed measurements of basic parameters.

Design of low order high OSR discrete time delta-sigma modulator for audio applications
Dohnal, Jaroslav ; Kledrowetz, Vilém (referee) ; Háze, Jiří (advisor)
Tato diplomová práce si klade za cíl seznámit čtenáře se základním konceptem a principy jednosmyčkových modulátorů . Diplomová práce ozřejmuje čtenáři problematiku delta-sigma () modulátorů s jednou zpětnovazební smyčkou. Zabývá se základními principy převzorkování u číslicově-analogových převodníků a rozšiřuje je o teorii tvarování spektra šumu. Vycházeje z této teorie jsou navrženy tři jednosmyčkové modulátory, které běží na 1024 OSR jako alternativa k běžně používáným modulátorům vysokých řádů. Modulátory jsou implementovány do FPGA společně s rekonstrukčním filtrem a podpůrnými bloky. Nakonec byl zkonstruován hardwarový prototyp pro vyhodnocení implementace navrženého DAC.

Design of Differential Difference Amplifier in CMOS technology
Trojan, Vladimír ; Khateb, Fabian (referee) ; Kledrowetz, Vilém (advisor)
The bachelor's thesis deals with the design of differential difference amplifier (DDA) in technology TSMC 0,18 with maximum input and output common mode range, minimum power dissipation and area on chip. The thesis describes the basics of CMOS technology, commonly used structures of analog integrated circuits and operational amplifiers. Main focus of the thesis is design of circuit of DDA. Designing and simulations of DDA parameters were made in program Cadence Virtuoso and ADE Assembler simulation environment. Layout of DDA was designed in Layout XL environment.

High effective switched power supply
Rástočný, Martin ; Kledrowetz, Vilém (referee) ; Pavlík, Michal (advisor)
This bachelor’s thesis analyses theoretical basis of switched mode power supplies. Selections of right topology for implementation, design of power and control circuits are discussed. The thesis also contains a brief summary of switched mode power supplies. Subsequently it focuses on calculations and selection of appropriate power components. A result of the thesis lies in development and practical design of switched mode power supply and its optimization for high effectivity of conversion. To achieve these theoretical calculations of parameters for chosen topology were made.

Error analysis and optimization of low voltage BG reference
Koukol, Martin ; Kledrowetz, Vilém (referee) ; Prokop, Roman (advisor)
The bachelor’s thesis deals with the design of Brokaw type low-voltage BG reference and it’s following optimalization using error analysis to achieve better precision than ±0,5 % with level of accuracy 4 sigma. The main focus of the thesis is the error analysis itself and finding the individual factors that affect precision. Design and optimalization of the voltage reference were made in program Cadence Virtuoso.
