基于ADS6122和FPGA的多通道信号采集系统的设计
Design of Multichannel Data Acquisition System Based on ADS6122 and FPGA
摘要
Abstract
A design of multichannel data acquisition system for ultrasonic imaging based on FPGA is implemented. A circuit with ADS6122 A/D converter is implemented, in which the highest sampling frequency can be 65MSPS. FPGA is used to control the logic,a data acquisition system for sampling one channel higher frequency signal and for sampling multi-channel lower frequency signals is implemented. The test results show that the sampling rate and sampling precision can meet the high requirements of the ultrasonic signal acquisition when the channel analog signal input frequency is less than 7 MHz. This system can also be referred to design other related multi-channel acquisition system.关键词
