Abstract
A system, method, and device for amplifying the signal of a photodiode are provided. The exemplary system may have a photodiode with an amplifier. The amplifier may have an amplifier inverting input, an amplifier non-inverting input, and an amplifier output. A photodiode of the system may have a photodiode anode electrically connected with the amplifier inverting input and a photodiode cathode electrically connected with the amplifier non-inverting input. A gain resistor of the system may couple the amplifier inverting input with the amplifier output. The system may also have a fixed voltage reference electrically connected with the photodiode cathode and the amplifier non-inverting output.
