| Research Abstract |
In this work, a radiation detector using a CMOS chip has been studied. PET as a plastic scintillator generates ultraviolet light, and the light is detected by single-photon avalanche diode (SPAD) implemented on a CMOS chip. A bias voltage generation is very important to improve SPAD sensitivity. A SPAD array is self-calibrated for excluding defect-elements and having high bias voltage. A clock generation is also required to measure a dark count, and it is used for the calibration. A low-power and accurate on-chip clock generator is realized by using only standard cells.
