Novel Pixel-Chip-Based Region-of-Interest Readout Design
his paper presents a novel pixel chip readout scheme: the Region-of-Interest Readout Circuit (ROIRC), which is designed for large area, large array pixel chips and Gas Pixel Detector (GPD). This design employs a sentinel pixel detection strategy, enabling rapid identification and prioritized readout of the pixel regions containing signal events. During the scanning readout of these signal events, ROIRC employs a Block-based readout approach, effectively minimizing the readout of non-signal pixels. The functionality of ROIRC has been successfully implemented on both the ASIC and FPGA platforms. In the tests of the ROIRC, the detector is capable of detecting low-energy X-rays in the range of 2-10 keV and support multiple event readouts, and the detector can perform effective readout of effective photons with a flux of up to 15k (cm-2 s-1) .
