Analysis Of Crosstalk in Binary Weighted Bulk Acoustic Wave Transducers For Ultrasonic Based Fourier Transform Accelerators

This paper introduces an ultrasonic wave-based analog computing accelerator for 2D-FT computation. The investigation centers on two distinct pixel cell designs within the accelerator, highlighting the potential of one design to address scalability and fabrication challenges. The study compares segregated and unified binary weighted BAW transducers as transmitter, along with a comparative assessment of coupling between the two designs through modeling, simulation and experimental analysis. The result shows minimal difference in the crosstalk for both designs, supporting the scalability of the transmitter array for enhanced resolution.
