Description
Summary:This paper is devoted to analyzing the effect of gamma radiation on the behavior of optocouplers. According to a series of experiments that involve masking various parts of a chip from X-ray irradiation, the most sensitive region of the chip is determined and the design of the optocoupler is improved. Upon modification, the radiation hardness of the device more than triples.
