Single-Crystal AlN Wafer-Based Bulk Acoustic Resonators for Piezoelectric Power Conversion
Ziqian Yao, Clarissa Daniel, Kaicheng Pan +5
In this work, we demonstrate the first single-crystal aluminum nitride (AlN) wafer-based thickness-extensional (TE) mode bulk acoustic resonator for piezoelectric power conversion.…
Radial Mode Lithium Niobate Rosen Transformer
Ziqian Yao, Heather Chang, Eric Stolt +4
In this work, we demonstrate the first two-port radial-mode Rosen transformer based on 36Y-cut lithium niobate (LN) for piezoelectric power conversion. The device achieve…
Periodically Poled Piezoelectric Lithium Niobate Resonator for Piezoelectric Power Conversion
Ziqian Yao, Clarissa Daniel, Lezli Matto +8
As the demand for compact and efficient power conversion systems increases, piezoelectric power converters have gained attention for their ability to replace bulky magnetic inducto…
Lithium Tantalate Bulk Acoustic Resonator For Piezoelectric Power Conversion
Ziqian Yao, Clarissa Daniel, Eric Stolt +3
We present the first lithium tantalate (LT) thickness-extensional (TE) mode bulk acoustic resonators designed for piezoelectric power conversion, showcasing a low temperature coeff…
Lithium Niobate Resonators for Power Conversion: Spurious Mode Suppression Via an Active Ring
Vakhtang Chulukhadze, Eric Allen Stolt, Clarissa Daniel +2
In an effort to shift the paradigm of power conversion, acoustic resonators pose as compact alternatives for lossy magnetic inductors. Currently, the acoustic resonator's restricte…
