Abstract :In this paper, a novel BJT-based class AB electronically tunable plus-type differential difference current conveyor (EDDCC+) is proposed, in which a translinear circuit principle is utilized. The current gain of the proposed EDDCC+ can be easily adjusted externally. Electronically tunability is provided by current sources in the translinear loop. The proposed EDDCC+ is simulated through the SPICE program to indicate the functionality of the proposed EDDCC+, where a previously published KHN filter is used as an application example. AT&T CBIC-R (N-2X and P-2X) transistor model parameters are used in the simulation of this circuit. Simulation results of the KHN filter verify theoretical calculations. The cut-off frequency of the low-pass, high-pass, and band-pass filters in the KHN filter circuit has been electronically changed.
