相邻周期抖动(Cycle-to-cycle jitter),顾名思义,指的是相邻的两个时钟周期之间的周期长度差异,如下图所示。第一个时钟周期长度为9.9ns,与之相邻的第二个时钟周期长度为10.2ns,所以相邻周期抖动为10.2-9.9=0.3ns。实际测量时要选择多个周期样本。需要注意的是相邻周期抖动只关注两个连续周期之间的周期长度变化,并不...

[DCDrms,DCDpkpk] = jitterDutyCycle(___,Name=Value) measures DCD using name-value arguments. Unspecified arguments take default values. [DCDrms,DCDpkpk,C] = jitterDutyCycle(___) measures the rms and peak-to-peak DCD using the above arguments. It also estimates the correlation information fo...
When the operating frequency is 700 MHz, the measured peak-to-peak jitter and rms jitter is 17.6 ps and 2.0 ps, respectively. 展开 关键词: All digital Cycle-controlled delay unit (CCDU) Delay-locked loop (DLL) Phase-locked loop (PLL) Successive-approximation-register (SAR) ...
This detailed T0 contour is required to obtain most of the time-domain perturbation measures used in Vocal Quality assessment (i.e. jitter, shimmer, and many forms of harmonics-to-noise ratios). Any types of cycle-to-cycle PDA can provide the necessary T0 contour for the cal- culation of...
The proposed CDR, on the other hand, quickly achieves phase and frequency lock to an incoming data using a few preamble bits then starts frequency tracking to compensate a tiny frequency offset due to jitter and quantization error. The reference-clock-less feature of the proposed CDR also ...
Its operating frequency range is from 200 MHz to 2 GHz. The power consumption and RMS jitter are 3.24 mW and 1.49 ps at 2 GHz, respectively. The active area of this chip is 0.011 mm2. This is a preview of subscription content, log in via an institution to check access. Similar ...
High-energy phase-stable sub-cycle mid-infrared pulses can provide unique opportunities to explore phase-sensitive strong-field light–matter interactions in atoms, molecules and solids. At the mid-infrared wavelength, the Keldysh parameter could be much
