要約(英語): Low power consumption and high temperature operation are important in an environmental monitoring system. The power consumption of 3mW is achieved for the radiation sensor using low voltage operational amplifier and comparator in the signal processing circuit. The leakage reverse current of photodiode causes the charge amplifier saturation over 50℃. High temperature durability was improved by optimizing the circuit configuration and the values of feedback resistance and capacitance in the charge amplifier. The pulse response of the radiation sensor was measured up to 55℃. The custom detection circuit was designed by 0.6μm CMOS process at 5V supply voltage. The operation temperature was improved up to 65℃.
