Abstract
A photodiode-amplifier circuit with the photodiode in the feedback pat h is presented. It is named the PIF-circuit. No resistor is needed at the amplifier input to provide a path to ground for the signal and lea kage currents from the photodiode and the amplifier input bias current . Therefore, one potentially dominating noise source is eliminated. At frequencies below 10 kHz, the implemented PIF-circuit has an NEP almo st-equal-to 3 fW/square-root H-z.
