A 0.6-V 1.6-GHz 8-phase all digital PLL using multi-phase based TDC

All-Digital PLL Frequency and Phase Noise Degradation Measurements Using Simple On-Chip Monitoring Circuits

Using simple on-chip monitoring circuits, we precisely characterized the impact of hot carrier injection and bias temperature instability on frequency and phase noise degradation of a 65nm all-digital PLL circuit. Experimental data shows that PLL phase noise degrades with aging even though the output frequency is maintained constant due to the PLL feedback operation. Results show that applying ...

Programmable Frequency Divider Design for Multi – Ghz Phase Locked Loop (PLL) System

The objective of this project is to develop a Programmable Frequency divider design for multi GHz PLL System implementation on FPGA using VHDL (hardware description language). The frequency divider architecture features 6 parallel divider chains, each one of them implementing a single division ratio. The desired frequency division ratio is then selected using the four control bits of an output ...

Design of All Digital Phase Locked Loop (d-pll) with Fast Acquisition Time

A Digital PLL is designed with improved acquisition time and power efficiency. The implemented D-PLL can operate from 6.54MHz to 105MHz with a power dissipation of is 7.763μW (at 210MHz) with 1.2V supply voltage. The D-PLL is synthesized using cadence RTL compiler in 45nm CMOS process technology.

Phase-space representations are of increasing importance as a viable and successful means to study exponentially complex quantum many-body systems from first principles. This paper traces the background of these methods, starting from the early work of Wigner, Glauber and Sudarshan. We focus on modern phase-space approaches using non-classical phase-space representations. These lead to the Gaus...
