amplifier. Charge is multiplied as it progresses from stage to stage in the multiplier toward the charge detection
node. The charge multiplication level depends on the amplitude of the multiplication pulses (approximately 11
V~15 V) applied to the multiplication gates. Due to the double length of the register, the first line in the field or
frame scan does not contain valid data and should be discarded.
readout and video processing
The last element of the charge readout and detection chain is the charge detection node. The charge detection
node uses standard floating diffusion (FD) concepts followed by dual stage source followers as buffer amplifiers.
The reset gate is internally connected to SRG1. This results in simultaneous FD resets when the SRG1 gate
is clocked high. To achieve the ultimate sensor performance, it is necessary to eliminate kTC noise using CDS
processing techniques. The IMPACTRONTM devices can detect single photons when cooled or when
sufficiently short integration times are used.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltage values are with respect to substrate terminal.
2. Peltier cooler generates heat during cooling process. To keep case temperature range, the heat must be removed through external
heat sink.
