Wireless Localization Module with Low-Power Firmware Based on RTOS
Lipka, Radim ; Bardonek, Petr (referee) ; Šimek, Václav (advisor)
This thesis focuses on the design and implementation of the wireless localization module, using UWB technology with emphases on low-power firmwre based on RTOS. Wireless localization is based on TDoA algorithm. The resulting HW module is designed as a four layer PCB, based on MCU crf52832 (ARM Cortex M4) and UWB module DevaWave DW1000. Firmware is implemented using FreeRTOS with emphasis on low power consumption. For hardware implementation, Eagle CAD was used. Firmware is implemented in C and Assembly programming languages.

Preamplifier for biological signals processing
Derishev, Anton ; Prokop, Roman (referee) ; Khateb, Fabian (advisor)
The work deals with the design and optimization of amplifiers in CMOS technology with low supply voltage and low power consumption. The main aim is to design an amplifier to amplify the biological signal. The first part is a brief introduction to the theory of biological signals. The work also contains a brief description of the biological signal processing methods and their properties. The important part is the description of the methods to reduce the supply voltage of the amplifier. The practical part of this thesis focuses on the design amplifiers with low supply voltage and low power consumption. All active elements and application examples have been verified by PSpice simulator using the 0.18 µm TSMC CMOS parameters. Simulated plots are included in this thesis to illustrate behavior of structures.

Design of low voltage low power Op-Amp
Kužílek, Jakub ; Háze, Jiří (referee) ; Khateb, Fabian (advisor)
This work deals with issues of design and optimize of an operational amplifiers using CMOS transistor models. The main focus of work is to propose a circuit suitable for low voltage applications with low power. The proposed circuit consists of sub-circuits, each of which must operate in the desired voltage range. Detailed design of input and output stages will reach range of rail-to-rail type with a minimum quiescent current.

Design of low-voltage operational amplifier
Sysel, Jan ; Šteffan, Pavel (referee) ; Khateb, Fabian (advisor)
This work deals with the design of operational amplifier with extremely low supply voltage and low power consumption. In the theoretical part is presented theory dealing with the structure and design of operational amplifier. In the following part are desribed design methods suitable for realization of low-voltage circuits. In the next part were designed two operational amplifiers using low-voltage design methods. Properties of these operational amplifiers were then tested by simulations.

Low Voltage Low Power Analogue Circuits Design
Alsibai, Ziad ; Horský, Pavel (referee) ; Ďuračková, Daniela (referee) ; Khateb, Fabian (advisor)
Disertační práce je zaměřena na výzkum nejběžnějších metod, které se využívají při návrhu analogových obvodů s využití nízkonapěťových (LV) a nízkopříkonových (LP) struktur. Tyto LV LP obvody mohou být vytvořeny díky vyspělým technologiím nebo také využitím pokročilých technik návrhu. Disertační práce se zabývá právě pokročilými technikami návrhu, především pak nekonvenčními. Mezi tyto techniky patří využití prvků s řízeným substrátem (bulk-driven - BD), s plovoucím hradlem (floating-gate - FG), s kvazi plovoucím hradlem (quasi-floating-gate - QFG), s řízeným substrátem s plovoucím hradlem (bulk-driven floating-gate - BD-FG) a s řízeným substrátem s kvazi plovoucím hradlem (quasi-floating-gate - BD-QFG). Práce je také orientována na možné způsoby implementace známých a moderních aktivních prvků pracujících v napěťovém, proudovém nebo mix-módu. Mezi tyto prvky lze začlenit zesilovače typu OTA (operational transconductance amplifier), CCII (second generation current conveyor), FB-CCII (fully-differential second generation current conveyor), FB-DDA (fully-balanced differential difference amplifier), VDTA (voltage differencing transconductance amplifier), CC-CDBA (current-controlled current differencing buffered amplifier) a CFOA (current feedback operational amplifier). Za účelem potvrzení funkčnosti a chování výše zmíněných struktur a prvků byly vytvořeny příklady aplikací, které simulují usměrňovací a induktanční vlastnosti diody, dále pak filtry dolní propusti, pásmové propusti a také univerzální filtry. Všechny aktivní prvky a příklady aplikací byly ověřeny pomocí PSpice simulací s využitím parametrů technologie 0,18 m TSMC CMOS. Pro ilustraci přesného a účinného chování struktur je v disertační práci zahrnuto velké množství simulačních výsledků.
