Design of Low Power Phase Locked Loop (PLL) Using 45NM VLSI Technology

International Journal of VLSI Design & Communication Systems, 2010
Power has become one of the most important paradigms of design convergence for multi gigahertz communication systems such as optical data links, wireless products, microprocessor & ASIC/SOC designs. POWER consumption has become a bottleneck in microprocessor design.

A Novel Coordinated Control Strategy for VSG to Enhance Power Tracking Speed Without Degrading Inertia Support Capability

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
ABSTRACT The virtual synchronous generator (VSG), as a representative grid‐forming control method, has become a key technology in distributed renewable energy systems. However, there exists an inherent trade‐off between fast power reference tracking and high virtual inertia support in conventional VSG control.

An adaptive gain phase‐locked loop for position sensorless control of permanent magnet synchronous motor drives

IET Electric Power Applications
In view of the cost and reliability issues caused by mechanical position sensors, position sensorless control (PSC) of permanent magnet synchronous motors (PMSMs) has received widespread attention. A series of rotor position estimation (RPE) schemes have

WFH: A Wideband Frequency Hopping‐Based Anti‐Jamming Navigation Signal Structure

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
Given the limitations of existing satellite navigation signals in antijamming performance amid growing environmental jamming, this paper proposes a navigation signal structure based on wideband frequency hopping (WFH) modulation to enhance both antijamming capability and measurement accuracy. It further introduces the nonstationary effective carrier‐to‐

Quadrature demultiplexing using a degenerate vector parametric amplifier [PDF]

, 2014
We report on quadrature demultiplexing of a quadrature phase-shift keying (QPSK) signal into two cross-polarized binary phase-shift keying (BPSK) signals with negligible penalty at bit-error rate (BER) equal to 10−9.

Blocking Interference Mechanism in Networked Radios Under UWB HPM

IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.
This paper conducts a systematic cross‐level analysis of the damage mechanism encompassing ‘electromagnetic interference–hardware impairment–communication performance’ for QPSK‐based networked radios. Using ultra‐wide spectrum pulse signals as the interference source, the study considers the scenario where electromagnetic interference causes damage to ...
