Random Telegraph Noise Modeling for Circuit Analysis: RTN in Ring Oscillators
IEEE Journal of the Electron Devices Society, 2022 In highly scaled MOSFETs, random telegraph noise (RTN) can decrease the reliability and yield of circuits. RTN is produced by charge trapping, which in large devices results in $1/f$ noise.

Acoustic Measures Capture Speech Dysfunction in Spinocerebellar Ataxia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Spinocerebellar ataxias (SCA) are hereditary cerebellar degenerative disorders with a common feature of dysarthria, involving impaired phonatory and articulatory control of speech, thereby affecting social communication. In this study, we investigated whether acoustic measures could objectively measure speech dysfunction and identify

Masking Noise and Jitter-Detection Thresholds [PDF]
The Journal of the Acoustical Society of America, 1969 Is the detection of temporal irregularity, or auditory jitter, dependent upon the availability of specific spectral frequency regions? An attempt was made to answer this question by obtaining jitter-detection thresholds in the presence of band-limited noise. Maximum effect is obtained by masking noise at intermediate spectral frequencies, in the region
