A novel off-state gate RHBD technique to mitigate the single-event transient(SET)in the differential data path of analog circuit is demonstrated in this paper.Simulation results present that this off-state gate technique could exploit charge sharing in differential circuits and reduce differential mode voltage perturbation effectively.It is indicated that this technique is more effective to mitigate SET than the differential charge cancellation(DCC)technique with less penalty. 展开更多
