ADC performance drift trade-off: a case study

Abstract

Characteristics of ADCs and performance drift under irradiation are often the critical points concerning the performance of equipment operating in hostile radiative environment. A presentation is given of the results obtained on 8 bit ADC manufactured in high speed bipolar technology (fT=8 GHz). A comparison between rad hard ADC and rad tolerant ADC is also presented in order to show the impact of technological choice on irradiation and electrical performances.
