Model for readout electronic noise as a function of sensor leakage current (considered to be one of its main sources) for different values of the diode capacitance, Cd. The model makes use of a number of circuit parameters each measured or estimated by other means. The measured noise value (from the energy resolution measurements discussed below) is 80 to 100 electrons RMS. Hence we infer that we understand the dominant noise sources and have a guide both analytical and from SPICE for future sensor-ROIC improvements.
