A 1.4psrms-period-jitter TDC-less fractional-N digital PLL with digitally controlled ring oscillator in 65nm CMOS

- 18 Mar 2010
TL;DR: State of the art digital PLLs can be divided in two categories, depending on the implementation of the digital phase detector, which allow fractional-N synthesis, but require high architecture complexity, need calibration routines for period normalization, and introduce analog limitations that a digital P LL should be intended to eliminate.

- 28 Mar 2013
TL;DR: Solutions that merge the key performance of the bang-bang architecture with fractional-N operation as in [3] are needed in order to turn thebang-bang digital PLLs into real alternatives to TDC-based PLLS.

Frequency synthesizer with injection locked oscillator

- 08 Apr 2015
TL;DR: In this paper, an edge of a reference signal is injected at various points within the oscillator, and replaced for the edge of the generated oscillation signal at the injection point, which reduces jitter for a controlled oscillator.

A Simple Simulation Approach for the Estimation of Convergence and Performance of Fully Adaptive Equalization in High-Speed Serial Interfaces
Davide Menin,Alessio De Pra,Andrea Bandiziol,Werner Grollitsch,Roberto Nonis,Pierpaolo Palestri +5 more
TL;DR: A novel approach to simulate the convergence and the performance of high-speed serial interfaces with adaptive equalization that uses as input the pulse response of the channel that is then modified by adaptive techniques implementing feed-forward, decision-feedback, and linear-continuous time equalization.

Analysis of Spurs Impact in PLL-Based FMCW Radar Systems
Luigi Grimaldi,Dmytro Cherniak,Werner Grollitsch,Roberto Nonis +3 more
- 01 Oct 2020
TL;DR: Insight is provided on spurs impact in PLL-based chirp generators for radar sensors by means of a time-domain model of the FMCW Radar transceiver for target detection, and the effect on the range FFT and on Doppler shift of the base-band signal is presented.
