Abstract: A system for ultrasound beamforming is provided, including a sampled analog beamformer, an array of ultrasound transducers, and a high voltage amplifier coupled to the sampled analog beamformer and the array of ultrasound transducers. The sampled analog beamformer includes a sampled analog filter for filtering an incoming analog signal and adding a fractional delay, and transmitting a filtered analog ultrasound signal. The array of ultrasound transducers further transmits the filtered analog ultrasound signal. The high voltage amplifier drives transducers in the array of ultrasound transducers.

Abstract: Systems and methods of implementing a more efficient and less resource-intensive CNN are disclosed herein. In particular, applications of CNN in the analog domain using Sampled Analog Technology (SAT) methods are disclosed. Using a CNN design with SAT results in lower power usage and faster operation as compared to a CNN design with digital logic and memory. The lower power usage of a CNN design with SAT can allow for sensor devices that also detect features at very low power for isolated operation.
