DOI: 10.1109/tcsii.2023.3260088
Abstract: An on-chip frequency-domain analog processor inspired by frequency-scanned arrays is proposed for broadband spectrum sensing. It exploits frequency-dependent constructive and destructive interference based on an array of programmable dispersion-engineered elements. Digitally programmable dispersion is implemented… read more here.

DOI: 10.1109/tmech.2020.2978241
Abstract: The article describes two new methods for driving piezoelectric tube scanners. The first method aims to maximize horizontal and vertical scan range by driving the internal electrode rather than grounding it. This approach eliminates the… read more here.
