Design of Differential Difference Amplifier in CMOS technology
Trojan, Vladimír ; Khateb, Fabian (referee) ; Kledrowetz, Vilém (advisor)
The bachelor's thesis deals with the design of differential difference amplifier (DDA) in technology TSMC 0,18 with maximum input and output common mode range, minimum power dissipation and area on chip. The thesis describes the basics of CMOS technology, commonly used structures of analog integrated circuits and operational amplifiers. Main focus of the thesis is design of circuit of DDA. Designing and simulations of DDA parameters were made in program Cadence Virtuoso and ADE Assembler simulation environment. Layout of DDA was designed in Layout XL environment.
Design and optimization of special low-level amplifier for measurement of air ions
Zdražil, Lukáš ; Bartušek, Karel (referee) ; Roubal, Zdeněk (advisor)
This Master thesis deals with low-current measurement in order of picoamps up to a few tens of femtoamps. Such low currents measuring is necessary for determination of air ions concentration. Disturbances, which are otherwise negligible for ordinary measurements must be considered. For example, leakage currents and noise generated in measuring device circuit. The choice of a precise operation amplifier with low input bias current is as important as the selection of low noise passive components. The aim of the thesis is to design and implement a precise low-level amplifier for the purposes of air ions concentration measurements.
Comparative analysis of professional texts
Mošnerová, Tereza ; Krhutová, Milena (referee) ; Zmrzlá, Petra (advisor)
Tato bakalářská práce analyzuje tři odborné texty z oblasti elektrotechniky. Prvním textem, který byl pro tuto analýzu zvolen, je vysokoškolská učebnice, druhým je populárně naučný vědecký článek a třetím technická přednáška. Všechny texty seznamují čtenáře s tématem operačních zesilovačů. Tato práce komentuje zmíněné žánry a jejich typické znaky, avšak jejím hlavním záměrem je analýza kohezních řetězců. Analyzována je jak gramatická a lexikální koheze, tak výskyt a užití klíčových výrazů v kohezních řetězcích. Všechny položky kohezních řetězců jsou vloženy do několika tabulek a je zjištěn procentuální výskyt jednotlivých kategorií. Vychází najevo, že v každém z vybraných textů lexikální koheze značně převažuje nad gramatickou, přičemž zajímavé rozdíly jsou dány srovnáním jednotlivých textů a kohezních prostředků v nich se vyskytujících.
Meassurement PC rad based on I51 microcontroller
Klezla, Petr ; Kaňa, Zdeněk (referee) ; Bradáč, Zdeněk (advisor)
The main topic of the thesis is to suggest and realize the measuring card with analog inputs and outputs. In the first part of this thesis we are concerned with key-elements of measuring cards, respectively ADC and DAC, and here are explained all their activities. Then we attend of choosing parts for suggested measuring card as is voltage reference, power supply and operational amplifier. Among others we are concerned with a question of protecting inputs against overvoltage and reversing of polarity and beside against disturbance. Then follows analysis of used microcontroller ADUC831 with description of its used outskirts. Here is described the stored for measured samples of MMC memory, how to work with it and the programme service. The last chapter describes suggested firmware and servicing programme for PC. In fine we value the quality of measuring card and its mistakes.
