A phase shifting multiple filter design methodology for Lucy-Richardson deconvolution of log-mixtures complex RTN tail distribution

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.
