High-overtone mode piezoelectric transformer based on c-axis zigzag ScAlN multilayer for wake-up receiver applications

The efficiency of RF-to-DC conversion in rectifying antennas in wake-up receivers significantly diminishes at lower RF power levels. In this study, we propose passive high-overtone bulk acoustic wave type piezoelectric transformers composed of an input layer (c-axis tilted ScAlN single-layer)/an aco...
