Rail-to-rail CMOS operational amplifier
Buček, Vladimír ; Bajer, Arnošt (referee) ; Musil, Vladislav (advisor)
The object of this project was to get acquainted with proposal of operational amplifier of technology CMOS. Primarily was analyse the structure of transistors PMOS and NMOS, thanks to them we could gradually suggested single blocks of operational amplifier. The work treats about proposal of differential pair, current mirror and the ending stage of amplifier. After the proposal of single blocks was done control of operational amplifier by simulation programme CADENCE.

Design of audio frequency amplifier for PC sound card
Chalupa, Petr ; Bajer, Arnošt (referee) ; Musil, Vladislav (advisor)
This work deals with the problems of low frequency amplifiers that are specialised in processing an analog music signal, that is get from output element of an sound card of an computer. A part of my work is a design of an amplifier, an design verification by calculations and simulations and subsequent production of amplifier. The end of my work is specialised in measurement parametres of amplifier and comparing them with german norm DIN 45 500.

Design of CMOS operational amplifiers
Němec, Tomáš ; Bajer, Arnošt (referee) ; Musil, Vladislav (advisor)
This work deals with issues of design and simulation of analog integrated circuit. The general aim is to design high-speed transconductance differentiating amplifier. The two stage operational – transconductance amplifier with compensation RC element is presented. This compensation method of zero nulling used prevents amplifier from oscillation.

CMOS Transconductance Amplifier Design
Zelinka, Miloslav ; Bajer, Arnošt (referee) ; Musil, Vladislav (advisor)
The work deals with question of design and simulation of integrated analog circuits in CMOS technology. The general aim of my thesis is to design transconductance amplifier and analyze its frequency response and stability in feedback systems. The two stage operational – transconductance amplifier with compensation capacitor is presented in my work. This compensational method of pole splitting used together with the nulling resistor prevents amplifier from oscillation. This work also deals with circuit solution of computing amplifier. It verifies compensation influence of frequency for phaser and frequency characteristics.

Microposition control device
Kokeš, Ondřej ; Bajer, Arnošt (referee) ; Kadlec, Jaroslav (advisor)
Presented thesis analyses a function of the particular type of the nanopositioner with aim to suggest and construct an electronic device suitable for control of the nanopositioner slider. In presented material there is a description of the control signals and possibility of their generating in the respect of slider movement accuracy. The main goal of the thesis is to describe electronic units ranging from power supply, control processor unit part to end part that directly joint nanopositioner. There is also programme equipment for microcontroller and computer, communication description, movement measuring and calibration and draft for the close-up of the control loop for additional increase of the movement accuracy.
