Currently, a 16-channel ultrasound phased array system has become a common configuration in the commercial market, but the complexity and cost of developing such a system are still high. The research objective of this paper is to develop a 16-channel ultrasound phased array system and study its analog front-end (AFE) design.In this study, we will implement a 16-channel ultrasound phased array system, which includes ultrasonic transmitters, receivers, amplifiers, analog-to-digital converters and corresponding control circuits and software. In terms of AFE design, we will study how to design a low-noise, high-gain and low-power template amplifier, and how to implement analog multi-path anti-aliasing design and dynamic gain control.We will use analog circuit and digital signal processing techniques to implement our system design, and conduct experimental testing and performance evaluation. The research results will enable us to better understand the 精品文档---下载后可任意编辑working principles and performance characteristics of ultrasound phased array systems and promote future technology development and application promotion.Keywords: ultrasound phased array imaging; 16-channel; analog front-end (AFE); template amplifier; multi-path anti-aliasing; dynamic gain control.
