Switching capacitor array used in electrical tunable filter suffers from using too much capacitor and the capacitance always nonstandard. This paper proposes a strategy based on particle swarm optimization algorithm to obtain the needed capacitance through the combination of standard capacitance. Finally, the simulation result of an example proves that this approach can achieve the needed capacitance as well as reduce the number of capacitor significantly.
