Analog Circuit
Circuit schematic for an analog FE board.
This illustration shows four circuits, on the FE board the VLPC circuits are connected into groups of 64 channels.
Each group has
a common BIAS supply on the board and a shared trace into the cassette.
the common bias supply circuit is also the common signal return.
The 64 individual
signal lines are
also bias return lines.
For charge splitting the single capacitor shown coupling the signal into the MCM is replaced with a charge division network
