Abstract
Various aspects include circuits and methods for use in X-ray detectors for obtaining time information regarding when an indication of an X-ray photon's energy, such as a CSA output voltage, and using the time information to obtain temporal-spectral data regarding an X-ray photon detection. The temporal-spectral data may be used to determine the X-ray photon's energy, to detect and account for multiple X-ray photon detection events (“pile ups”), and/or accommodating detection events in which charge is shared between two pixel detectors.
