Prediction Of Electrostatic Discharge Soft Error On Two-Way Radio Using Simulation And Immunity Scanning Technique

Electrostatic discharge (ESD) is a major cause of failures and malfunctions in two-way communication radio. Soft error failures like logic error, latch-up and wrong reset can occur as a result of the excessive ESD. It is a well-known fact that the Complementary Metal-Oxide- Semiconductor (CMOS) d...

Electronics. Nuclear engineering Electrostatic discharge (ESD) is a major cause of failures and malfunctions in two-way communication radio.

It is also predicted that the soft error due to ESD would occur at 11 kV and 8 kV for improved and original radio respectively.
