Current amplifier circuit diagram.
The photodiode absorbs energy from light and releases electrons thereby acting as an input current source. In negative feedback the amplifier introduces a phase shift of 180 o into the circuit while the feedback network is so designed that it produces no phase shift or zero phase shift. A small modification has been made since this article was published the base emitter resistor for the voltage amplifier stage q2 in figures 1 and 2 has been reduced from 10k to 2 2k and if you wish to experiment you may wish to reduce it further. When the feedback circuit is allied in series through the o p as well as the input then both the o p impedance the i p impedance will be increased.
