This paper presents a new design of complementary oxide semiconductor voltage controlled oscillator (CMOS VCO) for improve tuning range and phase noise with low power consumption. Design is area efficient and easy to implement. Design is carried out in cadence and schematic editor using 180 nm technology. Simulation is done and performance results are reported. Results have been compared with e...
The front-end readout channel consists of a charge sensitive amplifier (CSA) and two different unipolar-shaping circuits to generate pulses suitable for time energy measurement. signal processing chain the single is built parallel paths: fast path with peaking 30 ns obtain arrival each particle impinging detector; slow 400 dedicated low noise amplitude measurements, which formed by pole-zero ca...
A new electrostatic discharge (ESD) implantation method is proposed to significantly improve ESD robustness of CMOS integrated circuits in subquarter-micron CMOS processes, especially the machine-model (MM) ESD robustness. By using this method, the ESD current is discharged far away from the surface channel of nMOS, therefore the nMOS (both single nMOS and stacked nMOS) can sustain a much highe...
Background and Objectives: Working length determination is one of the most important factors in successful root canal treatment; therefore, this study was carried out to compare conventional (E-speed) and digital (CMOS) radiographies in determining the working length of the root canals of mandibular molar teeth. Materials and Methods: In this ex-vivo study, 25 permanent mandibular double-roo...

Although GH treatment for short stature in Turner syndrome is an accepted treatment in many countries, which GH dosage to use and which age to start puberty induction are issues of debate. This study shows final height (FH) in 60 girls with Turner syndrome treated in a randomized dose-response trial, combining GH treatment with low dose estrogens at a relatively young age. Girls were randomly a...
Hyperventilation (HV) and respiratory alkalosis are associated with hypophosphataemia, although the extent and duration of HV required to produce changes in serum phosphate levels are not known. We sought to characterize the effects of HV, with or without dextrose loading, on serum phosphate levels and other biochemical parameters. HV was monitored by controlling the end-tidal partial pressure ...
