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.

Electronic circuits with active elements at current mode
Bačkovský, Pavel ; Sedláček, Jiří (referee) ; Murina, Milan (advisor)
This bachelor’s thesis deals problems with current feedback amplifiers and their comparison with voltage feedback amplifiers. Then it adverts to mutual differences and compares their parameters. This thesis shows basic circuits with current sources and with power boost of this circuits. This thesis designs conception of current source. Simulation, complete details for realization of current source, drawing printed circuit and specification card used parts are part of this work. In the end this work the parameters of current source are checked.
