Abstract
Disclosed are circuits for automatic calibration of the gain of electronic amplification and digitization systems for use with X-ray detectors. The calibration is based on injecting predetermined pulses into the electronic system and deriving a calibration ratio based the digital value of their amplitude with the digital value of the same pulses, unamplified and digitized with a high accuracy reference ADC. All ADCs, as well as the DACs used to control the pulser amplitude are referenced to a single common reference voltage. Calibration for non-linearity of the gain is disclosed with an alternative embodiment for the same circuits.
