摘要
介绍了一种适用于生物电极输出的微电流动态检测装置 ,其通过对基底电流的采样及动态补偿 ,以及多种抗干扰和降噪设计 ,测量精度达到 0 .1nA ,使生物电极反应的定量分析成为可能。
A kind of dynamic feeble current measuring device for biologic electrode is introduced.The design lays high emphasis on compensating background current,eliminating interference and noise. With these effective measures,high precision at 0.1 nA can be got, which makes quantitative analysis possible.
