Design of anti-aliasing filter for discrete-time delta-sigma modulators
Vogel, Vojtěch ; Háze, Jiří (referee) ; Kledrowetz, Vilém (advisor)
This work deals with the design of a second order anti-aliasing filter with a cutoff frequency in the order of hundreds of kHz using the switched capacitor technique. The use of this technique allows the design of accurate and tunable analog circuits without the use of resistors. In this work, the design of analog switches is described. Furthermore, the various circuits required for the design of the filter in the onsemi I3T80 technology are proposed.
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 of a New Structure of an Active Filter on Transistor Level
Michalička, Filip ; Dvořák, Jan (referee) ; Bečková, Zuzana (advisor)
Bachelor's thesis deals with designs of new structures of active frequency filters which operate in voltage mode using active element designed on transistor level. The first part describes parameters and kinds of basic frequency filters and types of aproximation. The second part contains a briefing of unipolar transistors, MOS transistor and his properties. The next part deals with method of signal flow graphs and describes the topology of leap-frog frequency filters. Practical part shows transistor based design of an operational transconductance amplifier using transistors TSMC 0,18 µm from the Taiwan Semiconductor company and designs of two new structures of frequency filters using leap-frog topology. Last part presents schematic diagrams from simulation programms. Verification the function of the operational transconductance amplifier and analysis of the new filter structures is performed by simulation programms OrCAD Capture and PSPICE.
Operational transconductance amplifier (OTA) for Field Programable Mixed-Signal Arrays
Czajkowski, Ondřej ; Háze, Jiří (referee) ; Bečvář, Daniel (advisor)
Operational amplifier will be designed and optimized with respect to set of required parameters. Real CMOS technology (available at Department of Microelectronics) will be used for designed OTA circuit and its simulations. Designed OTA will be used as universal operation amplifier configurable block in FPAA (field-programmable analog array) structures.

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.
