	Abstract – The pulsed ionizing radiation effect of monolithic operational amplifiers is investigated using a flash X-ray facility. The experimental results show that the pulsed ionizing radiation produces voltage surges in the devices and the output voltage recovers linearly after transient disturbance which includes a negative peak and a positive peak. The recovery time depends on the amplitude of the positive peak and the inherent slew rate of the devices. The degradation of transient disturbance amplitude and the recovery time versus ionizing dose rate of pulsed X-rays is researched. The relationship of circuit effects to physical mechanisms is investigated in detail. The photocurrent induced by transient ionizing radiation in the PN junctions in integrated circuits is responsible for the electrical degradation. Keywords – Transient ionizing Radiation effect, Transient disturbance, Photocurrent, integrated circuits
