Design of a New Structure of an Active Filter on Transistor Level
 Michalička, Filip ; Dvořák, Jan (referee) ; Bečková, Zuzana (advisor)
Bachelor's thesis deals with designs of new structures of active frequency filters which operate in voltage mode using active element designed on transistor level. The first part describes parameters and kinds of basic frequency filters and types of aproximation. The second part contains a briefing of unipolar transistors, MOS transistor and his properties. The next part deals with method of signal flow graphs and describes the topology of leap-frog frequency filters. Practical part shows transistor based design of an operational transconductance amplifier using transistors TSMC 0,18 µm from the Taiwan Semiconductor company and designs of two new structures of frequency filters using leap-frog topology. Last part presents schematic diagrams from simulation programms. Verification the function of the operational transconductance amplifier and analysis of the new filter structures is performed by simulation programms OrCAD Capture and PSPICE.
