| Aug 18, 2021 at 12:27 | comment | added | Andy aka | It's a noisy phototransistor so try choosing one that has applications listed that imply a low noise. TIAs come with their own noise problems but you are not at this level yet. Pick a better device. | |

| Aug 18, 2021 at 9:33 | comment | added | Justme | Is there any reason why you chose that circuit configuration over a transimpedance configuration? | |
| Aug 18, 2021 at 9:32 | comment | added | Long Pham | For a multistage amplifier, the first amplifier stage is the most critical, system noise performance mostly depends on it. (en.wikipedia.org/wiki/Friis_formulas_for_noise) | |
