Comparative Study of Single Event Transient Effects on Dynamic Comparator in Bulk CMOS
Bibliographic record
Abstract
Dynamic comparators are critical components in analog-to-digital converters (ADCs), yet their reliability can be severely compromised by Single-Event Transients (SETs) in radiation environments. This work presents a comparative study of SET susceptibility across prominent dynamic comparator architectures, including the StrongArm latch and Double-Tail structures, with emphasis on the effectiveness of the Triple Modular Redundancy (TMR) mitigation technique. To further improve radiation resilience, we propose a Radiation-Hardened-by-Design (RHBD) dynamic comparator based on a modified StrongArm architecture, termed the StrongArm Quatro-Latch comparator. The proposed design incorporates structural enhancements aimed at suppressing SET-induced disruptions. Circuit-level simulations demonstrate that the Quatro-Latch architecture significantly improves SET tolerance while maintaining competitive performance in terms of speed, power, and area. Comparative analysis across all architectures provides insight into trade-offs between SET robustness and design metrics, confirming the proposed RHBD comparator as a compelling solution for dynamic comparator-based ADCs operating in radiation-prone environments.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
