10.3.1 Design Requirements

The objective is to design a low noise, wideband optical front-end system using a diverse selection of optical sensors: PD, APD, PMT, and MPPC with the OPA855 as the TIA. The approximate design requirements for each type of photodetector are listed in #GUID-DBE3AC82-1014-447C-8F4F-39DD98DA7AAD/GUID-7210CE8A-6BAF-4F85-9C55-E7F43CD2D199.
