This paper approaches the problem of dynamically reconfigurable filters design using the new technology of Field Programmable Analog Arrays (FPAAs). This implementation technique allows creating effective and robust reconfigurable filters that may be applied in various environments such as military, mobile communication and general industry. Based on the configurable analog blocks (CABs) system and Anadigm Designeer2 software, an interesting and promising idea to implement the dynamically reconfigurable filters is exposed. The system is practically implemented and verified by using an developing board equipped with an AN231E04 reconfigurable integrated device from Anadigm, and an PIC microcontroller that manage the connection between PC and the FPAA device. The programming of the AN221E04 is realised through a serial connection with the PC.
