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。

Normal working hours, B2-B1 between the need to add a positive voltage, E-B1 between the PN junction forward biased if the Canadian single-junction transistors that turn, after turn-on, E-B1 between the resistance will soon be reduced, to B2-B1 between the current rapid increase in current increase, so that the resistance between the E-B1 further reduced, so the formation of a strong positive feedback.

正常工作时，B2—B1间需加正电压，E—B1间的 PN结若加正向偏置，单结晶体管即导通，导通后，E—B1间的电阻会很快降低，使B2—B1间的电流迅速增加，电流的增加，又使E—B1间的电阻更进一步的减小，如此形成了强烈的正反馈。

The I-V characteristics of the diodes with 100μm diameter indicated that as the densities of V-defects on GaN films increased from 4.1×105cm-2 to 1.03×107cm-2, the Schottky barrier height decreased from 1.44eV to 1.19eV and the reverse bias leakage current at -1V is increased sharply from 10-10A to 10-7A . Further studies on a single V-defect using conductive atomic force microscope demonstrated that the value of forward current biased at 8V at V-defect side-walls appears to be one order higher than that of plain region, indicating that the conductivity mainly occurred at the side-walls of V-defect.
