Excerpt from Optical Radiation Measurements: Photometric Instrumentation and Research; 1970 to 1971

If RS 2 Rf, then this ratio is approximately one, for large A, hence this circuit is Often called a unity gain amplifier, Therefore, the voltage noise in this circuit is not very important unless R becomes greater than the photocell impedance. High frequency current noise can be a proglem at these high impedances. To overcome this a small capacitor can'
