Data aquisition card for integrated circuit tester
Koleček, Jan ; Pristach, Marián (referee) ; Dvořák, Vojtěch (advisor)
The goal of this bachelor's thesis is to design and realize a data acquisition card. The main task of the designed card will be to generate stimulating signals for the tested integrated circuit, to process signals generated by the tested integrated circuit, to convert them into a digital form and to send them to a superior system. The thesis will present a choice of integrated circuits suitable for its realization, a wiring diagram of the data acquisition card, PCB design and VHDL code for the control FPGA chip.

Design of class AB audio power amplifier
Hynek, Jiří ; Kratochvíl, Tomáš (referee) ; Brančík, Lubomír (advisor)
his thesis is focused on a proposal of an audio power amplifier of class AB with minimum capacity of 2 x 80 Watt and with a possibility to control the frequency characteristics, volume and balance. An usage of this proposal is wide today. The proposal is designed to be made from common available components. This thesis includes proposal of an acceptable power supply and proposal of an active cooling elements.

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.

High-frequency oscillator in CMOS technology
Lang, Radek ; Musil, Vladislav (referee) ; Prokop, Roman (advisor)
This project focus to desing an on-chip oscillator in function as a clock generator. Frequency stability of the oscillator is affected by supply voltage, temperature and process variations. The aim is to propose a clock generator with sufficient frequency stability, low power consumption and a small chip area. This work deals with the types of oscillators and their basic building blocks suitable for our application. It also deals with the study and design options of temperature and process compensation circuit generating the current control, which provides the frequency stabilization of the output signal.

Active electrical filters based on switched-capacitor circuits
Třeček, Stanislav ; Dostál, Tomáš (referee) ; Brančík, Lubomír (advisor)
This thesis deals with concept of universal frequency filter by application of a switched-capacitor functional block. The concept is based on the theory of switched-capacitor circuits and the theory of a design of classical frequency filters. The printed circuit board was designed based on the filter connection developed by using a software Eagle. The filter was implemented as a laboratory product. This product has been revitalized and the frequency response of all types of filters has been measured. The measured parameters were compared with the parameters set out in the technical documentation of functional block.
