一种快速采集保持器

A Rapid Sample/Hold Circuit,

地震数据采集系统中 ,采样 /保持器 (S/H)是一个基本电路器件。实际应用 S/H时必须严格考虑速度和精度两方面的要求。文章就地震数据采集系统中常用的反相闭环积分型 S/H的工作速度、传输精度 。

In the seismic data sample system,the Sampler/Holder is a fundmental electronic device.During actual application of S/H ,the requirements on both velocity and precision are strictly of consideration.Based on the operational velocity and transmission precision,the conventional antiphase closed loop integral S/H,a effective method of reapid and high precision data is presented and feasibility of this approach is demonstrated.
