As the need for precise, high performing imaging in applications such as medical imaging and high energy physics increases, so does the need for sensitive image detectors to capture crucial information and convert it to high-resolution images. Heterogeneous imaging addresses this by combining the advantages of non-CMOS photoconductive sensors with the flexibility and robustness of CMOS readout electronics. Heterogeneous imaging can open the doors to new and improved capabilities in X-ray and visible light imaging. This thesis describes the design of a readout amplifier for a heterogeneous X-ray camera based on amorphous selenium (a-Se) as a photoconductive material fabricated upon CMOS.
