Jitter and phase noise in ring oscillators [PDF]
IEEE Journal of Solid-State Circuits, 1999 A companion analysis of clock jitter and phase noise of single-ended and differential ring oscillators is presented. The impulse sensitivity functions are used to derive expressions for the jitter and phase noise of ring oscillators. The effect of the number of stages, power dissipation, frequency of oscillation, and short-channel effects on the jitter

SIGGRAPH Asia 2023 Conference Papers, 2023 We propose a method for implicitly generating blue noise point sets. Our method is based on the observations that curl noise vector fields are volume-preserving and that jittering can be construed as moving points along the streamlines of a vector field.

Low Cost and Precise Jitter Measurement Method for TRNG Entropy Assessment
Transactions on Cryptographic Hardware and Embedded Systems, 2023 Random number generators and specifically true random number generators (TRNGs) are essential in cryptography. TRNGs implemented in logic devices usually exploit the time instability of clock signals generated in freely running oscillators as source of ...

Sampling-Noise Modeling & Removal in Shape From Focus Systems Through Kalman Filter
IEEE Access, 2021 Shape from Focus (SFF) is one of the passive techniques to recover the shape of an object under consideration. It utilizes the focus cue present in the stack of images, obtained by a single camera.

Design and verification of data acquisition clock circuit based on dual-loop phase-locked loop
He jishu, 2022 Background Digital measurement system based on ADCs (analog-to-digital converter) has higher requirement on the signal to noise ratio (SNR) of sampled data. Among all the factors, the jitter of sampling clock has the most prominent effect on SNR.

Development of a tool to objectively identify normal human voice
BLDE University Journal of Health Sciences, 2020 Acoustic analysis is used to assist differential diagnosis, documentation and evaluation of treatment for voice disorders. Clinical data has shown that Jitter, Shimmer, Mean Pitch and Harmonic Noise Ratio are the indices of voice pathology.

IEEE Photonics Journal, 2019 We experimentally investigate the noise properties of a homemade 586 MHz mode-locked laser (MLL). The variation of the timing jitter versus the harmonic order is measured, which is consistent with the theoretical analyses.
