**R4 has been increased to a 1.5k resistor. This is to lower the gain of the circuit to compensate for the higher gain from the 50 micron SiPM.
**R4 has been increased to a 1.5k resistor. This is to lower the gain of the circuit to compensate for the higher gain from the 50 micron SiPM.
**Added R22 of 365 Ohms in parallel with R2.
**Added R22 of 365 Ohms in parallel with R2.
**Added C22 of 10nF in parallel with R2 and in series with R21. C21 and R21 were added to shift the frequency "bump" in the gain at low frequencies due to the increased values of R2, R3 and R4.
