A new configuration to realize the most general n-th order voltage transfer function is proposed. It employs only one operational transresistance amplifier (OTRA) as the active element. In the synthesis of the transfer fimction, the RC:-RC decomposition technique is used. To the best of the authors knowledge, this is the first topology to be used in the realization of an n-th order transfer function employing a single OTRA.
