摘要：
This paper introduces a new type of CMOS-based current conveyor: current controlled fully balanced second generation current conveyor (CFBCCII) element which has a pair of differential Y terminals, a pair of differential X terminals and two pairs of Z terminals. The proposed circuit offers electronic tuning possibilities by means of a current adjustable intrinsic resistance at its X terminal. An elliptic filter realization is described as an example for its application in a current-mode fully balanced filter design, where the intrinsic resistors in CFBCCIIs are used for the electronic tuning of the characteristic filter frequency.
