Methods for testing of analog circuits
Kincl, Zdeněk ; Vlček, Čestmír (referee) ; Husák, Miroslav (referee) ; Kolka, Zdeněk (advisor)
Práce se zabývá metodami pro testování lineárních analogových obvodů v kmitočtové oblasti. Cílem je navrhnout efektivní metody pro automatické generování testovacího plánu. Snížením počtu měření a výpočetní náročnosti lze výrazně snížit náklady za testování. Práce se zabývá multifrekveční parametrickou poruchovou analýzou, která byla plně implementována do programu Matlab. Vhodnou volbou testovacích kmitočtů lze potlačit chyby měření a chyby způsobené výrobními tolerancemi obvodových prvků. Navržené metody pro optimální volbu kmitočtů byly statisticky ověřeny metodou MonteCarlo. Pro zvýšení přesnosti a snížení výpočetní náročnosti poruchové analýzy byly vyvinuty postupy založené na metodě nejmenších čtverců a přibližné symbolické analýze.
Design of laboratory device with FPAA
Veselý, Jan ; Götthans, Tomáš (referee) ; Petržela, Jiří (advisor)
This paper discusses the properties and possibilities of programmable analog circuits (FPAAs), especially type AN221E04 and development board with such device. It also brings a way tu use this device in laboratory education to build frequency filters and oscillators.
Voltage and current reference sources
Skalický, Pavel ; Pavlík, Michal (referee) ; Háze, Jiří (advisor)
The topic of the master´s thesis are voltage and current reference sources. There is detailed description of current and voltage references, which are basic building blocks of many analog circuits, in the theoretical part. Next part of the master´s thesis is the design of a voltage reference source, the design of a voltage reference generating two voltages and a current reference source. The correct function of all circuits have been verified using simulations, especially dependence of the output voltage or current on supply voltage or dependence of the output voltage or current when the ambient temperature is changed.
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.
