Simulation and implementation of adaptive and matched filters using FPAA technology

This paper presents the results obtained in the simulation and implementation of adaptive and matched filters using the new technology of FPAA (Field Programmable Analog Arrays). The proposed filter structures are intended to be used in conditioning of signals from radiation sensors but can be also used in any application that necessitates signal extraction from noise. For the implementation of the filter were used configurable analog blocks (CABs) from Anadigm AN221E04 dynamically reconfigurable chip. The most important advantage of the proposed design is represented by the possibility to reconfigure the filter characteristics in order to meet application specific requirements.
