Abstract
Photo receiver circuits comprising photo diode, a first amplifier, a second amplifier, and a feedback resistor are disclosed. The photo diode receives a light signal producing a photo current and the circuit produces an output voltage proportional to the photo current. In one example, the second amplifier coupled across the photo diode provides a voltage level shift between the input terminal and the output terminal, bootstrapping the parasitic capacitance out.
