The Design Of Remote CMOS IC Radiation Online Dynamic Testing System Based On Virtual Instrument

Space applications have been seeing more and more CMOS integrated circuits as the manufacturing process and design level is getting more and more advanced. However, the physical characteristics of CMOS-based integrated circuits make it subjective to radiation environment in space. Therefore the anti-radiation techniques of CMOS integrated circuits have been in research long before and many researchers focus on the verification and measurement of CMOS integrated circuits under radiation condition.This thesis proposed a low cost measurement system for remote real-time monitor of radiation effects of CMOS integrated circuits, which is based on virtual instrument technology. The measurement system combined the advantages of domestic on-line and off-line test and has successfully been applied to the total ionizing dose and single event effect tests of a CMOS digital-analog converter circuit for several times, during which full-process and full-parameter on-line monitor was achieved. The test results and analysis of the measurement system are elaborated in the last part. This thesis is meant to provide a general thought on the full-process and full-parameter on-line monitor of radiation test of 10,000 gates scaled CMOS integrated circuits.
