Abstract :
An area-efficient design approach for implementing a fully programmable Nth order switched-capacitor filter is proposed. Since programmable capacitor arrays (PCAs) consume vast amounts of area the proposed approach makes use of time-multiplexing resulting in the need for only three PCAs.
