One subunit of the FEM circuit model for PSAPD. Cdetector is the PSAPD capacitance, isig is the photodetection signal and inoise is the combination of all the noise sources. Rresistive_sheet models the high resistivity layer on the n-doped side of the PSAPD that is connected to the spatial channels. Rlow_resistivity models the low resistivity layer that is connected to the common. This FEM section is replicated 100 times.
