Ideally, all of the photodiode current flows through the feedback resistor of Figure 1, generating an output voltage equal to the photodiode current multiplied by the feedback resistor. The Noise Gain of a Photodiode Amplifier Increases at Higher Frequencies The photodiode capacitance will dominate the total input capacitance in most systems, but some applications may require extra care in selecting an op amp with very low input capacitance. The Concept of a Programmable Gain Photodiode Amplifier The output noise of the amplifier is the input voltage noise multiplied by the amplifier’s noise gain.

In addition, the technical article gives the reader more such as offset, amplifier, the output noise, photodiodes, gain, signals, bandwidth, gain resistor, output noise, input offset, applications, temperature, amplitude, photodiode transfer function, low pass filter, detection, and voltage noise.
