Abstract :
A multifunction active R filter with two operational amplifiers, attractive for monolithic i.c. fabrication, is presented. It realises b.p., b.e. and l.p. transfer characteristics at three different output terminals. The resonant frequency of the b.p. characteristic can be controlled over a wide range with constant bandwidth and resonant gain.
