Synthesis of the electronically reconfigurable frequency filters
Michalička, Filip ; Dvořák, Jan (referee) ; Langhammer, Lukáš (advisor)
This diploma thesis deals with design of reconection-less electronically reconfigurable filter structures which have single input and single output using unconventional active elements, which have ability to adjust one of their parameter e.g. gain or transconductance. The first part describes basic parameters of frequency filters, the division of filters by frequency transfer response and used circuit elements, their operational modes, the principle of reconnection-less electronically reconfiguration and the circuit design method MUNV. Second part describes all active elements used in the proposal of filters, their properties and the implementation using existing transistor-level models. The third part contains the design of three reconnection-less electronically reconfigurable filters and the simulations results obtained from simulation programs OrCAD Capture and PSpice. The obtained results were compared with theoretical behaviour. This part also contains results of these analyses: sensitivity, parasitic, Monte Carlo and temperature to determine the behaviour in varied cases.

Detector of optical beam position
Lukáč, Vladimír ; Barcík, Peter (referee) ; Kolka, Zdeněk (advisor)
The bachelor's thesis deals with the design of an optical beam position detector with the required parameters. The aim was to select a suitable photodetector that captures light rays and converts them into photocurrent, to design photocurrent processing into a voltage signal with linear properties and specified parameters, to convert the analog form of the voltage signal into digital information with which a microcomputer or microcontroller can work. The analog part of the work is simulated in the program OrCAD PSpice, in which the functionality and correctness of the designs is confirmed. The digital part processes the voltage signal to the information of the used channel, its level displays this data on the display.

Frequency Filters with Controllable Current Followers
Novotný, Matouš ; Herencsár, Norbert (referee) ; Koton, Jaroslav (advisor)
Submitted work engage in suggestion and realization of frequency-selection filters with usage one or more active devices CMI (Current Mirror and Inverter). The preamble of thesis is applied to theory of frequency-selection filters and possible usage of them. The projected circuit layouts are discussed next to would be possible change some of choice parameters of frequency-selection filter. The part of thesis is numerical suggestion of found solutions, their simulation in suitable program and realization.

Design of electronically reconfigurable filtering structures with modern active elements
Prát, Marek ; Kubánek, David (referee) ; Langhammer, Lukáš (advisor)
The aim of master's thesis was design of electronically reconfigurable filters. Adjustability of pole frequency or quality factor is possible. First part of thesis deals with theoretical analysis of filters, their operation modes, design of frequency filters using Signal-Flow graph method and parasitic analysis. The next part describes active elements used in thesis. In a third part, three reconfigurable filters are described and designed and their simulations and parasitic analysis are made. Last part deals with filter design in EAGLE and experimental measurement.

Current mirror higher-order filters
Novotný, Matouš ; Herencsár, Norbert (referee) ; Lattenberg, Ivo (advisor)
Submitted work engages in suggestion of frequency-selection filters with usage of more active elements of the MCMI (Multi-Output Current Mirror and inverter). The preamble of thesis is applied to theory of frequency-selection filters and possible usage of them. The projected circuit layouts with the active elements are discussed in terms of the impact of parasitic properties of the real models. The part of thesis is numerical suggestion of found solutions, their simulation in suitable program.
