This brief presents a low-voltage and low-noise ring voltage-controlled oscillator (VCO) where the phase noise performance is improved by reducing total channel thermal injected into output node of VCO during transition period voltage swing. Implemented in 65-nm CMOS technology, proposed operates from 485.7 to 1011.6 MHz. At 645 MHz, measured -110.8 dBc/Hz at an offset 1 MHz while dissipating 10 mW 1-V supply.
In this study, in order to understand accurate calculation of greenhouse gas emissions urban solid waste incineration facilities, which are major and problems likely occur at time, were calculated by classifying methods into 3 types. For the comparison methods, characteristics ratio, dry substance content characteristics, carbon substance, 12C analyzed; particular, CO2 concentration gases analyzed together. types made through assay value, using each method, facilities then compared. As a...
The conventional cellular mobile device needs a tens-of-MHz main crystal oscillator (XO) and 32.768kHz real-time clock (RTC) XO for RF ultra-low-jitter PLLs sleep operation, respectively. To minimize BoM cost PCB area by reducing the number of crystals, low-power with fractional divider (DIV.) in [1] is reported RTC. However, high-power-consuming start-up operation high-Q-factor inevitable. on-chip RC (RCO) can be an alternative to RTC due its compact excellent stability over process,...
AbstractThe present study investigates the geometric effects of a 45-deg elbow on development and distribution local two-phase flow parameters in horizontal bubbly flow. A round pipe with an inner diameter 50.3 mm is used as test section throughout study. The consists 90-deg followed farther downstream by elbow. Local pressure measurements are made at three different axial locations, one upstream two In total, 15 conditions investigated for analysis. At measurement port just elbow, acquired...
