Optimization of fabrication technology for ceramics packages
Pavlas, Ondřej ; Szendiuch, Ivan (referee) ; Skácel, Josef (advisor)
This bachelor thesis „Optimalization of fabrication technology for ceramics packals“ tackles the issues of ceramic packaging technology for microelectronics applications. This thesis deals with experimental production of ceramic packages from milling to sintering and the dispense printing with a straight capillary a tan angle 45°
Design of Digital Circuits at Transistor Level
Kešner, Filip ; Šimek, Václav (referee) ; Vašíček, Zdeněk (advisor)
This work aims to design process of integrated circuits on the transistor level, specially using evolutionary algorithm. For this purpose it is necessary to choose reasonable level of abstraction during simulation, which is used for evaluation candidate solutions by fitness function. This simulation has to be fast enough to evaluate thousands of candidate solutions within seconds. This work discusses already used techniques for transistor level circuit design and it chooses useful parts for new design of faster and more reliable automated design process, which would be able to design complex logic circuits. The thesis also discusses implementation of this system and used approach with regard to encountered problems in transistor-level circuit design and optimization by evolution.
Study of Inserting Hardware Trojans into Processors
Šviková, Johana ; Šimek, Václav (referee) ; Růžička, Richard (advisor)
This bachelor's thesis focuses on a specific aspect of cybersecurity known as hardware trojans, which are insidious attacks integrated directly into electronic components. The work begins with an analysis of the architecture and function of hardware trojans, examining their various types and classifications, and exploring methods for their detection and prevention. Furthermore, the thesis investigates how these attacks can impact compromised devices and how they can pose serious security risks. This thesis contains a design and implementation of a Trojan horse for a simple processor.
Design of a wireless communication interface with a PC for an emulation platform for modeling integrated circuits
Benc, Marek ; Janůš, Tomáš (referee) ; Šteffan, Pavel (advisor)
In the design center of Onsemi in Rožnov pod Radhoštěm, they use an emulation platform based around an FPGA for verification and debugging tasks for certain integrated circuits, and it's equipped with an interface that models an IC's configuration fuses with physical switches. For ICs with large fuse counts, working with this interface is tedious and error-prone, which has lead to this thesis investigating the possibilities for creating a wireless configuration interface that would be controlled by a PC.
Optimization of integrated circuits large-area delayering process using advanced inspection technologies
Vlach, Marek ; Otáhal, Alexandr (referee) ; Chmela, Ondřej (advisor)
This bachelor thesis provides an overview of the technological methods used for decapsulation and delayering of integrated circuits. Furthermore, the inspection techniques and material analysis used during delayering of semiconductor chips are presented. The thesis also discusses the technological development of integrated circuits in terms of the transistor structures used. In the practical part of the thesis, a procedure for decapsulation and large-area delayering of integrated circuits is proposed and tested.
High-Voltage Structures for Galvanic Isolation in Integrated Circuits
Ptáček, Karel ; Husák, Miroslav (referee) ; Zemánek, Miroslav (referee) ; Boušek, Jaroslav (advisor)
Tato dizertační práce představuje novou techniku laterární rezonanční vazby, která je využita v návrhu galvanicky izolovaného posouvače úrovně, který je následně implementován v 800 V půlmůstkovém kontroléru pro průmyslové aplikace. Ve srovnání s tradičními galvanickými izolátory jsou výrobní náklady tohoto řešení nižší. Pro aplikace vyžadující vyšší úroveň galvanické izolace je popsán následný vývoj galvanicky izolovaného posouvače úrovně, který využívá pouze jeden galvanicky oddělený posouvač úrovní pro komunikaci v obou směrech, což výrazně snižuje plochu struktury izolátoru. Jako součást následného návrhu je představen galvanický izolátor který je schopen přenášet analogovou hodnotu napětí. Analogový izolátor byl testován v reálné aplikaci síťového spínaného zdroje jako náhrada standardního optočlenu. Tato konstrukce umožňuje integraci primárních a sekundárních obvodů v jednom pouzdře, což umožní snížit složitost a cenu spínaného zdroje.
Electronic Circuits for Biomedical Applications
Pisarenko, Tatiana ; Langerová, Petra (referee) ; Zmrzlá, Petra (advisor)
Tato bakalářská práce obsahuje úvod do biomedicínských signálů a možnosti zpracování těchto signálů elektronickými obvody. Významná část práce se zaměřuje především na popis EMG signálu. Součástí práce jsou take schemata elektrických obvodů, které se používají především pro zpracování EMG signálů. Dále má práce praktickou část, v níž byly v simulátoru OrCAD Capture ověřovány funkce a parametry navrženého obvodu.
LED driver with synchronous rectification
Hodáňová, Adéla ; Šotner, Roman (referee) ; Kubíček, Michal (advisor)
The main goal of this diploma thesis is to compare two circuits designed for LED powering with output current of units of Amperes. Both circuits are based on step-down converter topology, one with technology of synchronous rectifying and the other one without it. Calculations and selection of used components with real prototypes were made for both selected circuits. All selected components meet automotive qualification requirements for discrete products. Produced prototypes were compared in terms of functionality, efficiency, EMC and thermal radiation.
A Laboratory Task: Oscilloscope Measurement
Malý, Ondřej ; Steinbauer, Miloslav (referee) ; Marcoň, Petr (advisor)
Bachelor thesis deals with the design of a signal generator for a laboratory task of the subject HELE. As a generating chip is used ICL 8038 that can generate three types of waveform – sinus, square wave and triangle. The frequency range is from 20 Hz to 20 kHz in selected circuit. Output is connected to oscilloscope probe, but also to 3.5mm headphone jack through which can be the selected waveform listened to on the connected headphones or speakers and measure the audible threshold.
