Nanosecond, Nanometer Movies of MEMS/NEMS Dynamics in a Standard SEM Using Time-Tagged Secondary Electrons. [PDF]

Small Methods
For the observation of micromechanical devices, a fast imaging technique with high temporal resolution is needed. Here, we demonstrate that a standard scanning electron microscope can be converted into a time‐resolving instrument using a fast detector and a time‐to‐digital converter.

A Low-jitter Ring-DCO-Based Digital PLL Using P/I-Gain Co-Optimization and Optimally Spaced TDC for Flicker-Noise Reduction

, 2023
This work presents a low-jitter ring-oscillator-based digital PLL (RO-DPLL). To achieve low jitter, the proposed RO-DPLL used calibration techniques to optimize the gain of the Proportional-path (P-path) and Integral-path (I-path) in the digital-loop ...

JitSCA: Jitter-based Side-Channel Analysis in Picoscale Resolution [PDF]

, 2023
In safety and security conscious environments, isolated communication channels are often deemed necessary. Galvanically isolated communication channels are typically expected not to allow physical side-channel attacks through that channel.

Binary phase detector gain in bang-bang phase-locked loops with DCO jitter [PDF]

, 2010
Bang-bang phase-locked loops (BBPLLs) are hard nonlinear systems due to the nonlinearity introduced by the binary phase detector (BPD). In the presence of jitter, the nonlinear loop is typically analyzed by linearizing the BPD and applying linear ...

Algorithm based comparison between the integral method and harmonic analysis of the timing jitter of diode-based and solid-state pulsed laser sources [PDF]

, 2015
A comparison between two methods of timing jitter calculation is presented. The integral method utilizes spectral area of the single side-band (SSB) phase noise spectrum to calculate root mean square (rms) timing jitter. In contrast the harmonic analysis

Output-jitter performance of second-order digital bang-bang phase-locked loops with nonaccumulative reference clock jitter [PDF]

, 2011
Bang-bang phase-locked loops (BBPLLs) are inherently nonlinear systems due to the binary phase detector (BPD). While they are typically used for clock and data recovery, the ongoing trend toward digital loop implementations has resulted in several ...

Mutually Coupled Time-to-Digital Converters (TDCs) for Direct Time-of-Flight (dTOF) Image Sensors ‡

Sensors, 2018
Direct time-of-flight (dTOF) image sensors require accurate and robust timing references for precise depth calculation. On-chip timing references are well-known and understood, but for imaging systems where several thousands of pixels require seamless ...
