Adverse Effect of Inappropriately Implementing Source-isolation Mitigation Technique

Single event transient (SET) response was compared between various structures considering sourceisolation mitigation technique. The simulation results prove the existence of adverse effects. Besides bipolar amplification effects, both drive strength and node capacitance should be considered when trying to improve SET tolerance. Due to the nonuniqueness of related factors, unless one factor is definitely the main contributor, careful consideration and quantitative evaluation are highly suggested before implementing mitigation techniques.
