Analog Signal Processing with Integrated Current Feedback Amplifiers
Ben Ayad, Ibrahim R. H. ; Mikula, Vladimír (oponent) ; Šimčák, Marek (oponent) ; Musil, Vladislav (vedoucí práce)
This dissertation thesis deals with the design of new functional blocks usable in area of analogue signal processing. The current feedback circuits (which in a suitable configuration can operate in voltage or current mode) are used here. This allows to achieve very promising results in the systems with a very low power supply. The versatility of the circuits will find applications in many areas. The curreent-feedback amplifier is chosen as the main building block for the detailed studies on the analog signal processing circuit design and realisation through various RC configurations. The thesis deals mainly with the study, synthesis, and design aspects of deriving new immittance functions covering inductive and supercapacitive admittances, current conveyors, voltage conveyors, high quality selective filters utilizing the transimpedance, integrators and differentiators, non-minimum phase allpass equalizers, and voltage controlled oscillators. The work deals in detail with these new particular blocks which are described theoretically and evaluated by simulations.

Digital Programmable Building Blocks with the Residue Number Representation
Sharoun, Assaid Othman ; Mikula, Vladimír (oponent) ; Šimčák, Marek (oponent) ; Musil, Vladislav (vedoucí práce)
In the residue number system, a set of moduli which are independent of each other is given. An integer is represented by the residue of each modulus and the arithmetic operations are based on the residues individually. The arithmetic operations based on residue number system can be performed on various moduli independently to avoid the carry in addition, subtraction and multiplication, which is usually time consuming. However, the comparison and division are more complicated and the fraction number computation is immatured. Due to this, a residue number system is not yet popular in general-purpose computers, though it is extremely useful for digital-signal-processing applications. This thesis deals with the design, simulation and microcontroller implementation of some (residue number system based) building blocks for applications in the field of digital signal processing. The building blocks which have been studied are binary to residue converter, residue to binary converter, residue adder and residue multiplier. New algorithms were also introduced.
