TIA的转换g是反馈http://en.wikipedia.org/wiki/transimpedance_amplifier R.
你要衡量abvsolute光水平，或者只是简单地打开/关闭
基于一个简单的传感器，如反向偏置二极管？如果前者校准
传感器可从Avago，Rohm，VISHY等。如果后者只是一个比较器
TIA一般来说绰绰有余。事实上，你可以通过使用简单的方法来消除短暂性脑缺血发作。
一种基于R的光电池，如镉型细胞控制输入电平在分频器
比较器。在这个配置中设置比较器与歇斯底里。

The conversion G of the TIA is its fdbk R.
http://en.wikipedia.org/wiki/Transimpedance_amplifier
Are you trying to measure abvsolute light level, or just simply turn something on/off
based on a simple sensor like a reverse biased diode ? If the former calibrated
sensors are available from Avago, Rohm, Vishay, and others. If latter just a comparator
and TIA is generally more than enough. In fact you could eliminate TIA easily by using
a R based photocell, like a cadmium type cell controling input level in a divider to
comparator. Set the comparator up with hysterisis in this configuration.
