In analog circuit optimization, obtaining optimal point that can satisfy various kinds of specifications is posed as goal of design. Utilization of evolutionary algorithms was introduced as a useful method but speed of convergence and ensure to access optimal point are these method most challenges. In this paper the Multi-Layer Perceptron (MLP) artificial neural network is applied to access the suitable point appropriate different specifications values of analog circuit. This point used in optimization algorithm to find reliable response. Neural network itself is trained by training database is collected during initial optimization process. The link of HSPICE and MATLAB is used for circuit simulation and evaluation during the process.
