Abstract :
Two new current mode multifunction filter configurations are proposed with a single fully differential current conveyor (FDCCII). The first proposed current mode filter with single input and three outputs, which can simultaneously realize current-mode low-pass (LP), band-pass (BP), high-pass (HP), filter responses. The second proposed current mode filter with two inputs and two outputs, realize current-mode low-pass (LP), band-pass (BP), high-pass (HP) filter responses. Moreover, each of the proposed circuits employment two resistors and two capacitors. The presented circuits do not have element matching restriction. We performed simulations with SPICE simulation program using 0.35 ¿m TSMC CMOS technology. Simulation results are found in close agreement with theoretical results.
