A reconfigurable channel or band-select filter is one of the key elements of multi-mode analog front ends. This paper presents the system level aspects of a fully reconfigurable analog filter. The proposed circuit is based on analog array-like architecture that enables the mapping of low pass and polyphase band pass filters on a regular structure of reconfigurable unit elements. The current conveyor based topology represents a compromise between the generality of traditional field programmable analog arrays and the highly specialized requirements imposed by multi-mode wireless receiver architectures.
