Abstract

See full text

An embodiment of the present disclosure provides a method to reduce acoustic vibration in a multilayered capacitor stimulated by a radio frequency signal by placing a first capacitor layer adjacent to second capacitor layer sharing a common electrode such that the acoustic vibration is reduced by applying one or more anti-acoustic vibration bias voltages to the multilayered capacitor. Other embodiments are disclosed.
