The feedback resistance, R1, is dependent on cell sensitivity and should be chosen for either maximum dynamic range or for a desired scale factor. R2 is elective: in the case of photovoltaic cells or of photodiodes, it is not required in the case of photoconductive cells, it should be chosen to minimize bias current error over the operating range.

反馈电阻R1的取值由电池的灵敏度和要求的最大动态范围，或者需要的电流——电压转换比例决定。R2分情况选取：在光电池和光电二极管时不需要这个电阻，在光电导的时候，电阻的阻值应该能使在工作范围内，由OP输入偏置电流所带来的误差最小。

The n-type gate modulation could be explained by the bending effect of valence band in the Schottky-barrier junction.
