Realisation of Biquartic Filter Structures Using Transconductance Amplifiers

A possibility of the high order filter realisation using biquartic structures is given. Second-order sections with operational transconductance amplifiers (OTA) which are used as building blocks are shown and described. Sensitivities of discussed sections are shown and compared. Biquartic structure realisation using general second-order filters section is given. Finally, 8th-order BP filter is realised cascading two biquarts and measured characteristics is shown.
