What is the input dynamic range of a typical charge sensitive amplifier (CSA) ? It is possible to detect 1.5 Million photo electron by a CSA ? If yes then what is the output signal strength of such CSA. These photo electrons are produced by some number of multi-pixel avalanche photo diode array which has around 1.5 Million pixels all together.
What is the maximum output if all the pixels are fired simultaneously by photons in Avalanche Photo diode Multi Pixel Array having 135000 pixels. The signal from each pixel is added and there is single output.
