An advanced charge pump efficiency optimization methodology

In this paper, an advanced charge pump optimization methodology based on DOE technique is proposed. Compared with other optimization methods, this methodology constructs accurate mathematical models between the outputs and the input parameters with a few simulations through response surface technique and regression analysis. Moreover, owing to the simplification of the number of main charge pump input parameters and the addition of a practical constraint, this paper, for the first time, obtains the specific values of the input parameters which correspond to the highest output power efficiency. The verification shows, at this input condition, the value of the output efficiency is only 1.56% of error compared with the simulation result.
