Abstract :
Second order fully balanced active filter circuits that need few op amps are generated. Because the circuits are obtained from a general balanced structure with crossovers, in general they need fewer components than those obtained by transforming classical single ended filters such as the state variable filters, while retaining the advantages of ease-of-tuning and low-sensitivity
