“…In this section, we present a second-order current-mode band-pass filter based on impedance simulation [10]. The Figure 6 shows the implementation of this filter by using four plus-type current conveyors and two capacitors [36]. The two current conveyors (CCII+ (1) and CCII+ (2)) and capacitor (C1) are equivalent to the non-ideal inductance (i.e., an inductance having a parasitic positive resistance in parallel, see Figure 7.…”

This article presents an innovative implementation of the plus-type second-generation current conveyor (CCII+) using BiCMOS technology, which combines the benefits of bipolar and CMOS technologies. The optimization problem of minimizing the X-port input resistance and maximizing the current cut-off frequency value was solved using genetic algorithm (GA). The proposed approach allows the optimization of the BiCMOS CCII+ to achieve better performance compared to previous designs. As a practical application, a second-order band-pass filter using the optimized BiCMOS CCII+ was successfully realized. The performance of the proposed design was evaluated using SPICE simulations and compared with previously published works. This study shows that the BiCMOS CCII+ can be effectively optimized using GA to improve its performance, which has potential applications in various analog and mixed-signal circuits.

In this paper we highlight drawbacks of the use of a priori optimized current conveyor (CC) as basic building block of active circuits. We use the optimization based technique to act directly on the ports of the current conveyors encompassing the overall active circuits in order to make them behave as 'ideal' as possible by minimizing their parasitic effects, offsets, etc. Three active circuits are presented, namely two active filters and a simulated inductance. Obtained results are given and compared to the ideal ones and also to those reached using an 'optimized' building block.
