摘      要：In this paper, firstly we demonstrate the use of nodal admittance matrix to convert a low-pass band-pass filter based on operational amplifier（op-amp） to a circuit based on a second-generation current conveyor（CCII）. This technique allows us to get eight presumptions of filter circuits. Secondly, we present a novel architecture circuit of CCII, which can operate at low supply voltage of ±0.75 V. All simulations are performed by TSPICE models. The simulation results show that this circuit has a low impedance at terminal X（R X=1.01 Ω）, a very high input impedance at terminal Y, and wide bandwidth current and voltage. The center frequency of the proposed filter is variable on the interval [157 k Hz, 196 MHz].
