This paper introduces a method to limit overtone-mode on AT-Cut fundamental mode crystal resonator. According to the energy trapping theory, twice plating method is employed to increase the mass of the main electrode. The key design parameters are the diameter and thickness of the mass loading, which are determined so that the maximum ratio of the… (More)
