We demonstrate the utility of focused, pulsed X-rays for investigating localized total ionizing dose effects in bipolar analog integrated circuits. Using the LM139 comparator as a test vehicle, we show how the technique can be used to identify the so

A focused, pulsed x-ray beam was used to compare SET characteristics in pristine and proton-irradiated Al0.3Ga0.7N/GaN HEMTs. Measured SET amplitudes and trailing-edge decay times were analyzed as was the collected charge, obtained by integrating the

We investigate analog single event transient (ASET) generation in an LM124 operational amplifier using focused pulsed x-rays and 800 nm femtosecond laser pulses. We report improvements that have been made to the pulsed x-ray experimental apparatus wh

We report an experimental study of the transients generated by pulsed x-rays, heavy ions, and different laser wavelengths in a Si p-i-n photodiode. We compare the charge collected by all of the excitation methods to determine the equivalent LET for p
