Spectroscopic quantum imaging using pixel-level ADCS in Semiconductor-based Hybrid pixel detectors

This thesis describes the design of a microelectronic system that can be used to build a spectroscopic imaging system, in particular a spectroscopic quantum imaging using pixel-level ADCs in semiconductor-based hybrid pixel detectors. In such a system the signal generated in the sensor by a photon interaction is electronically processed to obtain a measurement of the energy deposited by the photon. This measurement is expressed as a digital value and read from the pixel by the appropriate circuitry located in the periphery of the chip. The digital data corresponding to the measurement (energy of the photon and pixel address in the imaging array) is then read from the chip by an external data acquisition system for further processing or visual presentation.
