Modification of 2. Ziegler -Nichols method.
Jaššo, Kamil ; Burlak, Vladimír (referee) ; Pivoňka, Petr (advisor)
This thesis will be focused on verification of usage of time-delay caused by discrete controller's converters for setting it's parameters by Ziegler-Nichols frequency method in cases when this method fails.
Electronic load
Škotnár, Martin ; Pavlík, Michal (referee) ; Boušek, Jaroslav (advisor)
This thesis deals with electronic load design. In the beginning of the thesis, the necessary theory for understanding the basic properties and principles of electronic loads is described. Current control is provided by a touch screen and a microprocessor. The work presents a detailed design procedure in terms of hardware and testing, as well as a printed circuit board design procedure. The result of the work is a fully functional electronic load. The main use consists in testing equipment such as power supplies and accumulators.
Audio Amplifier with Network Streaming and Sound Equalization
Liska, Matej ; Zeman, Kryštof (referee) ; Štůsek, Martin (advisor)
Diploma thesis contains the theory for the design and realization of a prototype audio amplifier device with the possibilities of digital or analog input content. It approach the features of D/A converter, analog filtering, volume control and amplification. Besides others, it describes the regulation of supply power voltages for individual active parts of device and approaches the software audio platform for acquisition and processing of audio data, including equalization. The thesis contains an general schematic design, created placement of individual components on board, including their table of descriptions and evaluation of the achieved results, including measured values and graphs.
General purpose analog signal converter
Strážnický, Martin ; Povalač, Aleš (referee) ; Kubíček, Michal (advisor)
This work deals with the design of a galvanically isolated converter of continuous analog signals and the design of a galvanically separated converter of digital TTL signals to HTL signals. The device is complemented by a STM32 microprocessor, which ensures the connection of analog input and output. The result of the work is the circuit structure of individual units, the results of simulations of important units, complete data for the production of device and measured values of individual units.
Design Of DA Converter With Fully Differential Output In CMOS Technology
Mácha, Petr
This work deals with the design of eight-bit digital to analog converter in technology I3T25 of ON Semiconductor company. The main goal is to design a converter with small size, and high transfer speed. The functionality of designed circuits is verified by simulation environment Cadence.
Precise fully differential audioamplifier
Hanousek, Filip ; Musil, Tomáš (referee) ; Pavlík, Michal (advisor)
The aim of this thesis is to design an amplifier for electrostatic and dynamic headphones with D/A converter integrated into one device. This device is controlled by a microcontroller The thesis deals mainly with the design, realisation and testing of all functional blocks of the device.
Design of current-steering DAC for differential IQ decoder
Klein, Miroslav ; Šotner, Roman (referee) ; Dřínovský, Jiří (advisor)
This master’s thesis deals with design of two channel digital to analog converter for automotive applications. In first part, different topologies of D/A converters and their properties are discussed, with focus on current steering topology. Second part deals with design of convertor topology and current steering application. In third part, all parts of designed convertor are described and simulations results are presented. The designed two channel D/A converter has differential current output with 11b resolution per channel.
Simulator of current output 0-24mA
Mačišáková, Kateřina ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
This bachelor thesis deals with design of very accurate current output simulator 0-24 mA with microcontroller with resolution 0.001 mA. In the thesis I deal with the market re-search with similar devices, theory and then with the conception of the whole system concept, with the identification of used components and with the evaluation of their suitability. I propose here a circuit diagram and a printed circuit board, which I then produce and install. For the resulting device I design and produce a box that will suita-bly complement and unify the entire system. I will revive the whole device, program it and test its functionality.
Simulator of voltage output 0-10V
Mačišák, Martin ; Baštán, Ondřej (referee) ; Bradáč, Zdeněk (advisor)
This bachelor's thesis deals with the design of the voltage output simulator in range of 0-10 V with microcontroller. The part of my bachelor's thesis is theoretical outline of whole system, draft of this system and draft of source. Further creation of wiring diagrams and PCB. Fitting of PCB and programming. This thesis checks up the functionality of the draft and also of whole system. Next outputs are compare with required outputs. Literary research is integral to my bachelor's thesis.
Simulator of voltage output -10V to +10V
Horváth, Michal ; Streit, Jakub (referee) ; Bradáč, Zdeněk (advisor)
This thesis is about voltage simulator with microcontroller. The thesis presents some of the available industrial concepts. After that custom design is being proposed of simulator. Hardware proposal includes schematic and printed circuit board design of simulator and power supply. After designing of hardware part, the thesis focuses on software developing. Eventually, the thesis focuses on measurement and discussing of measured results.
