A 20-GHz PLL With 20.9-fs Random Jitter

IEEE Journal of Solid-State Circuits, 2023
This article describes an integer- $N$ phase-locked loop (PLL) that incorporates a phase detector sampling both the rising and falling edges of the reference clock. The circuit also uses a new retiming method in the feedback divider.

A 12.5-GHz Fractional-N Type-I Sampling PLL Achieving 58-fs Integrated Jitter

IEEE Journal of Solid-State Circuits, 2022
This article presents a fractional-N sampling type-I phase-locked loop (PLL). To overcome the impairments of a conventional type-I PLL, namely the frequency-tuning-dependent time offset and the narrow range of the sampling phase detector (SPD), which ...

A 25.8GHz Integer-N PLL With Time-Amplifying Phase-Frequency Detector Achieving 60fsrms Jitter, -252.8dB FoMJ, and Robust Lock Acquisition Performance

IEEE International Solid-State Circuits Conference, 2022
With the rapid development of the modern communication technology, the communication standards impose stringent performance requirements, such as the ultra-low jitter requirement, on the phase-locked-loop (PLL) frequency synthesizers.

Jitter-Power Trade-Offs in PLLs

IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2021
As new applications impose jitter values in the range of a few tens of femtoseconds, the design of phase-locked loops faces daunting challenges. This paper derives basic relations between the tolerable jitter and the power consumption, predicting severe ...

Secrecy Performance Analysis of Air-to-Ground Communication With UAV Jitter and Multiple Random Walking Eavesdroppers

IEEE Transactions on Vehicular Technology, 2021
Flexible mobility and random jitter are two unique features of UAV communication platforms. Although advantages of mobility have been extensively explored, the random jitter of UAV platforms, caused by airflow and body vibrations, has been rarely studied.
