Dynamic range scaling scheme for the common signal. Cc_large and Cc_small form a capacitive divider. The common terminal of the PSAPD has a DC value of − 1750 V, which is blocked by the 1000 pF capacitor. The 1 MΩ resistor is necessary to ensure the DC value of node X remains at 0 V so that Cc_small and Cc_large do not need to be rated for high voltage.
