Design of a comparator with offset compensation in CMOS technology
Hylský, Josef ; Vávra, Jiří (referee) ; Kledrowetz, Vilém (advisor)
This work contains basic knowledge about comparators and its design in the CMOS technology. The first chapter deals with a wide use of a comparator, its charakteristice and the CMOS technology that is used to produce the transistors for the implementation of comparators. In the two following chapters there are examples of connexion of comparators, the design of the two-stage open loop comparator and improving of its charakteristic. The preamplifier and its application in high-speed Latchs comparators are introduced in the next chapter. The design of the comparator are introduced inthe next chapter. The design of the comparator and its application in high-speed comparators are introduced in the next chapter.

Active RC filters using CMOS technology
Veverka, David ; Kledrowetz, Vilém (referee) ; Háze, Jiří (advisor)
This work deals with issues of active RC filters and their application using CMOS technology. The work focuses on basic sumarization of fundamental knowledge about function of active RC filters but it also describes basic characteristics and parameters. The defined parameters are utilized in bachelors thesis. A research has been made about the current state in discussed topic and from this research there were derived parameters for simulations that are shown in the practical part of this work.

Modular approach to desing of modern analog devices in CMOS technology
Prokop, Roman ; Ďuračková, Daniela (referee) ; Hudec, Lubomír (referee) ; Musil, Vladislav (advisor)
The presented dissertation thesis deals with modular design of analog circuits in CMOS technology. The goal of the work is to design a set of modular microelectronic building blocks and realize the selected modern active circuits, working primarily in current mode. Nevertheless, the modular approach can be used for design of generally known classical elements, e.g. opamps, as well. As a part of the work, the development of the totally new highly versatile active circuit CCTA has been done, including detailed analysis of utilization and introduction of the most interesting applications. This circuit CCTA, together with relative, already theoretically treated circuit CDTA, has been realized here for the first time, in two different topologies. Final circuits were tested. On the basis of measurement results the library of behavioral models for PSpice was created, including exemplary simulations of the selected applications. Based on the obtained knowledge the brief comparison of voltage mode circuits and current mode circuits was done.

Analog switch for switched current circuits
Jahn, Michal ; Kledrowetz, Vilém (referee) ; Pavlík, Michal (advisor)
This bachelor’s deals with a design of analog switches using switched current technique and CMOS technology. The design of these switches was implemented and subsequently simulated in the CADENCE environment where the emphasis was on suppression of transient processes. It is a charge injection error and a clock-feedthrough error when charging the capacities of channel during switching on or opening.

Design of an AD converter for sensor applications
Bečková, Zuzana ; Kubánek, David (referee) ; Jeřábek, Jan (advisor)
Diplomová práce obsahuje stručný teoretický základ pro designéra/ku A/D převodníku v technologii CMOS a přehled architektur A/D převodníků používaných v automobilovém průmyslu. Volba vhodné architektury pro konkrétní aplikaci byla zásadním úkolem zpra- covaným v semestrálním projektu předcházejícím tuto práci a je rovněž součástí této práce. Analýza v Matlabu, ze které by mělo vyplynout, je-li třeba zahrnout do architek- tury podblok Sample and Hold, je také součástí práce. Klíčovou částí práce je dokumen- tace návrhu jednotlivých podbloků A/D převodníku – operačního zesilovače, kompará- toru a R-2R D/A převodníku – a ověření jejich funkčnosti. V závěru práce je ověřena funkčnost A/D převodníku jako celku.
