%X A new method of realizing elliptic ladder-type active bandpass filters is proposed. Comparing with the methods of the same category, it has the advantage of using fewer operational amplifiers, so the power consumption can be reduced. It also has the advantage of ease in adjustment. The low sensitivity property of ladder networks is maintained. The stability and the error of the fundamental circuits are analysed in detail. A sixth-order bandpass circuit is realized with this method and it shows that the evperimental resultsagree pretty well with the theoretical design.
