Understanding of the Coherent Demodulation with Phase-Locked Loop
MATEC Web of Conferences, 2018 The phase-locked loop (PLL) technology is a very important technology in the communication field. With the development of electronic technology toward digitalization, the phase-locked processing of signal needs to be realized in digital way.

Jitter Analysis and a Benchmarking Figure-of-Merit for Phase-Locked Loops [PDF]
, 2009 This brief analyzes the jitter as well as the power dissipation of phase-locked loops (PLLs). It aims at defining a benchmark figure-of-merit (FOM) that is compatible with the well-known FOM for oscillators but now extended to an entire PLL.

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

A design methodology to enable sampling PLLs to synthesise fractional-N frequencies [PDF]
, 2011 A novel design methodology is proposed to enable sampling phase-locked loops (SPLL) to synthesise fractional-N frequencies. To date, SPLL can only generate integer-N frequencies.

Insights Into the Antigenic Repertoire of Unclassified Synaptic Antibodies
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective We sought to characterize the sixth most common finding in our neuroimmunological laboratory practice (tissue assay‐observed unclassified neural antibodies [UNAs]), combining protein microarray and phage immunoprecipitation sequencing (PhIP‐Seq). Methods Patient specimens (258; 133 serums; 125 CSF) meeting UNA criteria were profiled;

A Novel Hybrid Control Approach for Frequency and Voltage Regulation in IPT Systems
IET Power ElectronicsThe purpose of the inductive power transfer (IPT) system is to deliver sufficient power from the power supply to the load via a magnetic coupler. To optimise the efficiency, transmission power, and stability of IPT systems, it is essential to sustain the
