In this paper, a new strategy of switchable CMOS phase-locked loop frequency synthesizer is proposed to increase its tuning range. The switchable PLL which integrates two phase-locked loops with different tuning frequencies are designed and fabricated in 0.5 μm n-well CMOS process. Cadence/Spectre simulations show that the frequency range of the switchable phased-locked loop is between 320 MHz ...

INTRODUCTION: The stiffness of a fixation construct affects the mechanism and progression by which a fracture heals. Locked plating constructs have improved fixation strength in weak bone, but their relatively high stiffness may suppress interfragmentary motion (IFM) to a level insufficient for optimal promotion of secondary bone healing.[1] This is especially of concern when locked plates are ...

BACKGROUND The purpose of this study was to compare the biomechanical properties of locked versus nonlocked lateral fibular bridge plating of comminuted, unstable ankle fractures in a mode of catastrophic failure. METHODS We created comminuted Weber C fractures in 8 paired limbs from fresh cadavers. Fractures were plated with either standard or locked one-third tubular bridge plating techniqu...

OBJECTIVES This study compares characteristics of public conservatees placed in locked facilities with those in less restrictive settings. Given the principle of the least restrictive alternative, the study seeks to identify factors, including the role of aging and advanced age, associated with restrictive placement within conservatorship. METHODS Management Information Systems data on 1,534 ...

OBJECTIVE The aim of the study was to examine the double locked-in phenomenon at work (i.e., being in a non-preferred occupation and non-preferred work place), and its associations to psychological health, physical health and job satisfaction. METHODS A total of 136 municipal employees who visited a career coaching center (response rate 59%) participated in the questionnaire study. RESULTS ...

We demonstrate experimentally new families of vector solitons with locked and precessing states of polarization for fundamental and multipulse soliton operations in a carbon nanotube mode-locked fiber laser with anomalous dispersion laser cavity.
