All-pass filters with various active devices
Novotný, Jakub ; Šotner, Roman (referee) ; Petržela, Jiří (advisor)
The theme of the semester project is to provide an overview of the function and use of analogue all-pass filters. It deals with their specific implementation using active functional blocks, i. e. using LT1228 transconductance amplifier manufactured by Linear Technology, using transimpedance amplifier AD844 manufactured by Analog Devices and using negative three port second generation current conveyor EL2082 manufactured by Intersil (formerly Elantec). Further outlines the concept of laboratory exercises on all-pass filters with the aforementioned integrated circuits. The exercise will consist of three separate units.

Design of the implementation project for house's electrical installation
Pitron, Jiří ; Drápela, Jiří (referee) ; Mastný, Petr (advisor)
The thesis deals with the design and process implementation project for house's electrical installation. The first section contains a statement of the necessary legislation, which is intended for the proper construction of the project. The following are practical examples on how to connect the object to the distribution network, basic furnishing and electrical wiring protection, design of electrical distribution lines and zone location. Continuing this part of the object is to provide external and internal lightning protection. This chapter introduces the reader how to design a receiver system, whose ground leads. It also describes the use of internal lightning protection, surge protection devices. The second part of this thesis examines the use and installation characteristics of the active elements, which may afford some extras to man. In the third practical part author compiled project of realization of wiring a house, which includes drawing circuits, devices and equipment into the house floor plan, electrometer housing scheme and also includes design drawing external lightning protection and its deployment. There are also necessary technical documentation with the economic evaluation of the created object.

Circuits for Analog Signal Processing Employing Unconventional Active Elements
Khatib, Nabhan ; Brzobohatý, Jaromír (referee) ; Zaplatílek,, Karel (referee) ; Biolek, Dalibor (advisor)
Disertační práce se zabývá zaváděním nových struktur moderních aktivních prvků pracujících v napěťovém, proudovém a smíšeném režimu. Funkčnost a chování těchto prvků byly ověřeny prostřednictvím SPICE simulací. V této práci je zahrnuta řada simulací, které dokazují přesnost a dobré vlastnosti těchto prvků, přičemž velký důraz byl kladen na to, aby tyto prvky byly schopny pracovat při nízkém napájecím napětí, jelikož poptávka po přenosných elektronických zařízeních a implantabilních zdravotnických přístrojích stále roste. Tyto přístroje jsou napájeny bateriemi a k tomu, aby byla prodloužena jejich životnost, trend navrhování analogových obvodů směřuje k stále většímu snižování spotřeby a napájecího napětí. Hlavním přínosem této práce je návrh nových CMOS struktur: CCII (Current Conveyor Second Generation) na základě BD (Bulk Driven), FG (Floating Gate) a QFG (Quasi Floating Gate); DVCC (Differential Voltage Current Conveyor) na základě FG, transkonduktor na základě nové techniky BD_QFG (Bulk Driven_Quasi Floating Gate), CCCDBA (Current Controlled Current Differencing Buffered Amplifier) na základě GD (Gate Driven), VDBA (Voltage Differencing Buffered Amplifier) na základě GD a DBeTA (Differential_Input Buffered and External Transconductance Amplifier) na základě BD. Dále je uvedeno několik zajímavých aplikací užívajících výše jmenované prvky. Získané výsledky simulací odpovídají teoretickým předpokladům.

Fully-differential frequency filter designing with current active elements using signal-flow graphs method
Štork, Petr ; Jeřábek, Jan (referee) ; Langhammer, Lukáš (advisor)
This master’s thesis deals with designing of fully-differential current-mode frequency filters using signal-flow graphs method. The first part is focused on a general description of frequency filters, its function and division. Active elements that create these frequency filters, such as multi-output current follower (MO-CF), balanced or multi-output transconductance amplifier (BOTA, MOTA) and digitally adjustace current amplifier (DACA) are described in the following part. Next, problems and various techniques of designing such filters are discussed on a theoretic basis. In the remaining part of the thesis there are six circuits of frequency filters described in detail; these connections are then transferred of passive elements to a proposed connections, with the assistance of a so-called reflection. Calculations of passive form are stated, as well as results of simulations, where nondifferential and differential variations of these designed frequency filters are compared. Finaly, it has been selected some variants of designs, which has been manufactured, then measured out and resulet has been compare between each other.

Reconfigurable multiband antenna
Havlín, Radomil ; Goňa, Stanislav (referee) ; Raida, Zbyněk (advisor)
This thesis deals with modeling and produce of reconfigurable multi-band planar antennas, which allow electrical shifting of frequency band. After antennas simulation with PIN diode and FET switch in a commercial program CST MW, another step is to optimize the antenna for a new substrate. The next step was to produce antennas. Finally, the optimized antennas are compared with the measurement on experimental antennas.
