摘　　要：文章介绍一种用CCD321型电荷耦合器件实现的微弱信号检测电路。用该器件设计的电路可以实现时域信号的取样积累,改善信噪比,有效地提取淹没于强噪声中的微弱信号。The weak signal detecting circuit being realized by CCD321 charge coupled device is produced in this paper,Which could sample and accumulate time-domain signals,improve the signal to noise ratio and extract the weak signals submerged in strong noise effectively.
