RHBD Technique for Single-Event Charge Cancellation in Folded-Cascode Amplifiers

A novel RHBD technique that exploits charge sharing is implemented in the single-ended gain stage of a folded-cascode operational amplifier to mitigate single-event transients (SETs). The efficacy of the technique is demonstrated via two-photon laser experiments. Using settling time as the primary metric for SET severity, the proposed layout technique achieves sensitive area reductions ranging from 41% to 95% with an overall area penalty of less than 1%.
