Design of sigma-delta digital-to-analog converter in CMOS technology
Soukup, Luděk ; Pristach, Marián (referee) ; Fujcik, Lukáš (advisor)
This master’s thesis deals with the issue of digital to analog conversion and possibility of its realization in digital circuits. Goal of this project is to design sigma-delta digital to analog converter with resolution of 14 bits and frequency band (0 ÷ 20) kHz. Main functional blocks: interpolator and modulator sigma-delta will be realized like digital structures. Reconstruction filter will be realized like an analog structure. For design a check of parameters of designed converter programs MATLAB and Simulink are used. Designed digital structures will be described by VHDL language.

Programmable load
Koleček, Jan ; Fujcik, Lukáš (referee) ; Pavlík, Michal (advisor)
The diploma thesis deals with the design of a programmable load. As first, the research of available commercial devices was made in the theoretical part. Based on this research, the design possibilities of programmable load were discussed. As next, the design of resistor network was made, using a computer program that was developed for this purpose. Practical part deals with a realization of module of load, control board and software development. Proposed system consists of control board and ten modules. Modules have floating input terminals. This approach facilitate to arbitrary combination of their inputs. Modules are designed to work with DC and AC power supplies.
