Abstract: This paper proposes a new method for sizing and optimizing CMOS cell circuit.The core algorithm is the niche-based genetic algorithm.The simulated result shows that the difference between the optimized circuit's performances obtained using the proposed method and that using the simulation-based method is not obvious, while the proposed method takes much less time.

Key words: optimization, performance analytic equation, fitness function, genetic algorithm, niche, cell circuit
