IV转换放大器 跨阻放大器 光电信号放大器 原理图及PCB设计分析 I-V转换最简单的方式就是串一个电阻，如图a，一般大电流的时候使用采样电阻R即可实现IV转换，再加上运放放大或者射随就可以ADC模块直接采集，在这里我们介绍的是微弱电流的IV转换，一般采用b形式的跨阻放大电路。首先在做跨阻放大的时候并不是所有的运放都适合跨阻放大电路，一般要选取高输入阻抗的运算放大器，根据需要转换的电流的大小，选取对应类型放大器，一般检测电流在nA到uA级的选用CMOS类型，例如TLC2201等芯片，在检测nA以下的电流的时候芯片的选型就变的比较重要了。首先在类型上要选JFET类型的，JFET类型的运放一般都有着极高的阻抗和低偏置电流的特性，例如ADA4530-1等芯片。在这里我们综合了性价比的情况，最终选型的是AD825芯片作为跨阻放大器。有着极低的偏置电流20pA和5*10^11的输入阻抗。具体参数可以看下芯片资料。
