Even order fully-differential biquadratic filter application of implementation of fully-differential OTA based on commercially available IC

This article presents a realization of a recently basic building block for analog signal processing, namely fully-differential operation transconductance amplifier (FD-OTA) using the commercially available ICs (LT1228). The proposed element has very simple internal instruction. The performances are examined through PSpice simulations. The description include example as even order fully-differential biquadratic filter topology. They show good agreement as theoretically depicted.
