Physics-based large-signal modeling of intrinsically tunable and switchable ferroelectric FBARs
An improved large-signal model for intrinsically tunable and switchable ferroelectric FBARs is presented. Ferroelectric FBARs based on multifunctional materials such as BST possess electric-field-tunable permittivity and electric-field-induced piezoelectricity. These properties are promising for the design of a new class of high-power reconfigurable RF devices for frequency-agile radios. Availability of a simple yet accurate large-signal model is indispensable when designing such devices. In this paper, an improved physics-based large-signal model is developed. Modeling results show great agreement with measurement results.
