Original Abstract
This paper deals with electronically reconfigurable current-mode filter with controllable pole frequency. The proposed filter contains these active elements: Current Conveyor Transconductance Amplifier (CCTA), Operational Transconductance Amplifier (OTA) and Adjustable Current Amplifier (ACA). The filter contains only single input and output (SISO). The filtering functions of the circuit can be electronically switched by current gain of the ACA elements without any reconnection in topology. The reconfigurable filter provides the ability to control pole frequency without disturbing quality factor. The PSpice simulator was used for verifying function of the proposed filter using available models of the active elements.
