The Single Event Effect (SEE) characterization of a Digital to Analog Converter showed an unexpected Single Event Transient (SET) dependence on operating conditions. The worst case condition resulting in the highest probability of an SET was at the highest supply voltage. The SET signatures were dependent on the input code, with some signatures not present when the input code was at mid scale. The... View full abstract»
