CMOS Transconductance Amplifier Design
Zelinka, Miloslav ; Bajer, Arnošt (referee) ; Musil, Vladislav (advisor)
The work deals with question of design and simulation of integrated analog circuits in CMOS technology. The general aim of my thesis is to design transconductance amplifier and analyze its frequency response and stability in feedback systems. The two stage operational – transconductance amplifier with compensation capacitor is presented in my work. This compensational method of pole splitting used together with the nulling resistor prevents amplifier from oscillation. This work also deals with circuit solution of computing amplifier. It verifies compensation influence of frequency for phaser and frequency characteristics.

Roughness measurement with laser profilometry
Mach, Radoslav ; Frk, Martin (referee) ; Hejátková, Edita (advisor)
The bachelor thesis deals with technology of laser profilometry for material roughness measurements purposes. The theoretical part deals with all aspects of the issue in an effective way and highlights the essential characteristics of used components and material roughness. The focus of this work is in first step to describe the external factors affecting the visual image processing such as increasing of environment temperature and its effect for a camera sensors. And particularly the relationship between CMOS and CCD technologies. The second step is for measuring roughness parameters of materials, such as metal, wood, rubber and plastic with three different lasers. Results demonstrate correlation between the wavelengths of the used laser lights with particular materials.

Evolutionary Circuit Design at the Transistor Level
Žaloudek, Luděk ; Vašíček, Zdeněk (referee) ; Sekanina, Lukáš (advisor)
This project deals with evolutionary design of electronic circuits with an emphasis on digital circuits. It describes the theoretical basics for the evolutionary design of circuits on computer systems, including the explanation of Genetic Programming and Evolutionary Strategies, possible design levels of electronic circuits, CMOS technology overview, also the overview of the most important evolutionary circuits design methods like development and Cartesian Genetic Programming. Next introduced is a new method of digital circuits design on the transistor level, which is based on CGP. Also a design system using this new method is introduced. Finally, the experiments performed with this system are described and evaluated.

Saving power and area with multi-bit pulsed latches
Král, Vojtěch ; Horský, Pavel (referee) ; Dřínovský, Jiří (advisor)
Diplomová práce se zabývá typy výkonových ztrát v technologii CMOS a následně jejich řešením metodami nízké spotřeby, které lze použít v oblasti zákaznických integrovaných obvodů. Jednou z možných metod pro nízkou spotřebu výkonu je vícebitový pulzní klopný obvod, který lze použít jako náhradu za standardní vícebitový klopný obvod typu master-slave. Vícebitový pulzní klopný obvod se skládá ze dvou částí, pulzního generátoru a pulzního klopného obvodu. V diplomové práci jsou popsané topologie, které mohou být použité. Konečná topologie byla vybraná na základě nízké spotřeby a plochy. Z vybrané topologie je vytvořeno schéma vícebitového pulzního klopného obvodu, které je porovnáno se schématem vícebitového klopného obvodu. Následně jsou vytvořeny layouty potřebných vícebitových pulzních klopných obvodů a porovnány jsou se standardními layouty vícebitových klopných obvodů. V závěru práce jsou navrhnuté vícebitové pulzní klopné obvody odsimulovány v jednoduchém designu.
