A divider-less PLL exploits a phase detector that directly samples the VCO with a reference clock. No VCO sampling buffer is used while dummy samplers keep the VCO spur <-56dBc. A modified inverter with low short-circuit current acts as a power efficient reference clock buffer. The 2.2GHz PLL in 0.18μm CMOS achieves -125dBc/Hz in-band phase noise with only 700μW loop-components power. Introduct...
Hydride formation was studied on Pd particles supported on SiO2, and the results were evaluated with reference to a corresponding ZnO-promoted Pd/SiO2 catalyst reported recently. Pd particles (mean size, ~5 nm) were epitaxially grown on NaCl(001) cleavage faces and subsequently covered by a layer of amorphous SiO2, thereby maintaining their epitaxial orientation. The films were subjected to var...
In situ X-ray photoelectron spectroscopy (in situ XPS) was used to study the structural and catalytic properties of Pd-In near-surface intermetallic phases in correlation with previously studied PdZn and PdGa.Room temperature deposition of ∼4 monolayer equivalents (MLEs) of In metal on Pd foil and subsequent annealing to 453 K in vacuum yields a ∼1:1 Pd/In near-surface multilayer intermetallic ...
Background: Medical adherence is critical to peritoneal dialysis (PD) success. Accordingly, the self-regulation approach plays a crucial role in disease management and treatment progress through the formation of an organized pattern of beliefs in patients. Aim: The purpose of this study was to compare the effects of self-regulation theory (SRT) and self-care training on medical adherence in pat...
To boost the performance of Large Hadron Collider (LHC) and increase potential discoveries after 2027, High-Luminosity LHC (HL-LHC) project has been announced, with aim increasing luminosity by a factor 10 above design value LHC. This will lead to an pile-up interactions negatively impact reconstruction objects in ATLAS detector, as well its triggering performance. In particular, at forward reg...
This paper contains suggestions for experiments with usage of the Spin Physics Detector (SPD) at first stage SPD NICA Programme developing JINR. Double polarized pp-, dd- and pd- collisions c.m.s. NN energies 3.4-10 GeV, which will be accessible initial experiments, allow one to study spin dependence interaction, search multiquark states double strangeness, charm beauty thresholds, short-range ...
In this paper, the performance of two low power phase frequency detectors is compared. A modified D-FF based PFD reduces the power consumption of traditional PFD to 4.732uW at 40MHz clock frequency and dead zone to 40ps.It is suitable for low power applications. A Falling Edge PFD uses only 12 transistors. This PFD operates up to 1GHz at 1.8V supply voltage. It consumes only 5.5uW when operatin...
OBJECTIVE To examine an association between melanoma and Parkinson disease (PD). PATIENTS AND METHODS Phase I: Rochester Epidemiology Project records were used to identify (between January 1, 1976, and December 31, 2013) patients with PD in Olmsted County, Minnesota, with 3 matched controls per case. After review, JMP statistical software with logistic regression analysis was used to assess t...
This paper presents a review of phase locked loop (PLL) techniques. The different types of phase detector, loop filter and oscillators are discussed. It alleviates the problems associated with the classical analog PLL. Linear PLL, Digital PLL and All digital PLL models are implemented in Simulink Simulation results in Simulink gives the performance overview of the three types of PLL. Keywords— ...
