The design of microelectronic systems is often complex, therefore metaheuristics can be of a great interest, because in most cases these systems have conflicting objectives and constraints.In this paper, we demonstrate the application of multi-criteria design strategies to a CMOS current conveyor.This provides designers with the ability to develop solutions that can meet several objectives respecting the design constraints.Therefore, three evolutionary algorithms well-known for their best performance in the resolution of more difficult multi-objective problems are proposed.They are first applied to the well-known benchmark functions and then for the optimal design of the current conveyor transistors in the framework of the 0.18µm CMOS technology.The aim is to maximize the bandwidth and minimize the parasitic input resistance respecting the technological constraints of the circuit.The obtained results are integrated in Cadence tool to show their validities.Final performances obtained by the three methods are in agreement and are better compared to the state-of-art-results.
