提出了一种多结构滤波器设计方法来改善 Lucy-Richardson 反卷积（LRDec）的收敛特性。需要解卷积来将随机电报噪声 (RTN) 尾部效应与整体 VLSI 时间相关的操作裕度特性解耦。所提出的并行滤波器设计减轻了反馈增益和反卷积目标的两个分布之间不必要的相位失准。与传统方法相比，相对反卷积误差降低了1.2个数量级。故障位概率预测精度提高100倍，收敛速度较传统算法提高33倍。
A multiple structure filter design methodology to improve convergence characteristics of the Lucy-Richardson-deconvolution (LRDec) is proposed. The deconvolution is required for decoupling the Random Telegraph Noise (RTN) tail effects from overall VLSI time-dependent operating margin characteristics. The proposed parallel filter design alleviates unwanted phase misalignment between the two distributions of feedback gain and deconvolution target. This reduces the relative deconvolution errors by 1.2-orders of magnitude compared with the conventional one. The prediction accuracy of fail-bit probability is increased by 100-folds while accelerating its convergence speed by 33 times of the conventional one.
