Abstract:In this paper, a novel active block for analog signal processing is presented, namely the current controlled current differential current conveyor (CCCDCC). This multi terminal block has most features of the well-known CCII (Second Generation Current Conveyor) and CCCDTA (Current Controlled Current Differencing Tranconductance Amplifier) to simplify the realization of current-mode analog filters suitable for signal processing. The proposed block and its applications were simulated in 0.18 μm CMOS process at ±0.9 V supply voltages. All of results were obtained by Hspice and with a high detailed transistor library. Keywords: current conveyor, filter realization, analog processing circuit, current differential, current-mode Classification: Integrated circuits References[1] A. Mahmoodi and A.
