Design of new V/I and I/V converters for the measurement of current-mode filters
Jarník, Lukáš ; Polák, Josef (referee) ; Langhammer, Lukáš (advisor)
This master’s thesis deals with problems of analog differential converters, which are used in measuring circuits working in the current mode. The aim of this thesis is to propose a new voltage to current and current to voltage converter, that should influence measured frequency properties as little as possible. Commercial active elements are use to design converters. Active components are compared on the basis of properties as bandwidth and slew rate. Designed converters are simulated in Orcad PSpice program. Converters, of the best behavior are practically implemented and measured. Measured and simulated values are compared.

Design of frequency filters with nontraditional active elements
Jarník, Lukáš ; Herencsár, Norbert (referee) ; Jeřábek, Jan (advisor)
Main topic of this semestral thesis is to design frequency filters with unusual active elements. They are presented active elements as are current conveyors (GCC), voltage conveyors (GVC), transconductance amplifiers (OTA, CFTA), which operate in current mode. Further the thesis contains six designed and simulated circuits with active elements (GCC), (CFTA), (OTA) and (GVC), which are based on according full admittance network. One designed was practically implemented and experimentally verified.
