High-order frequency filters using modern active elements
 Chrást, Jakub ; Minarčík, Martin (referee) ; Jeřábek, Jan (advisor)
The bachelor thesis deals with the designing of active frequency filters of the second – order which is useful for the construction of cascade high – order filters. These filters were designed by means of autonomous circuits. Multiple current mirror and inverter MCMI, current operational amplifier COA and current differencing transconductance amplifier CDTA were used as active elements. Designing is focused on the circuits using MCMI. Designed filters work in current mode. In the introductory part there are described general characters of frequency filters. The second part includes the methods of construction high – order filters, the third part contains the description of active elements used. The design we can find in the fourth part. The functionality of filters was verified by computer simulation. One of the optimal filters was practically verified by available component UCC 0520. Two other filters were used for the construction of the fourth – order filter.
