Abstract

Methods of designing a BAW resonator and filter and the resulting devices are provided. Embodiments include patterning a bottom electrode of a resonator; patterning a top electrode of the resonator; and intersecting areas of the top and bottom electrodes to provide an effective area of the resonator, wherein the effective area includes a closed-loop contour line including a pulse function pattern with pre-defined amplitude, period and a number of repetitions of pulses along the closed-loop contour line.
