With the rapid development of national economic level, people’s living standards have been greatly improved, leading to people’s higher attention to their daily diet. However, there are still a great number of people who have not realized the importance of healthy diet, which could result in many health problems such as under-nutrition or over-nutrition. The cooking process has a significant impact on food nutrition, thus a fast, convenient and healthy new cooking process has a great potential to be developed and applied in our daily life.
A tri-mode RF receiver with all digital automatic gain control (AGC) loop and non-uniform 2-bit analog-to-digital converter (ADC) is designed for the bands of GPS-L1, Galileo-E1 and Compass B1 in 0.18 lm CMOS process. The RF front-end, analog baseband and frequency synthesizer with voltage controlled oscillator (VCO) have been integrated, and there are only few offchip components including bypass capacitances, matching network and TCXO. For anti-jamming consideration, an all digital AGC loop with relevant variable gain amplifier (VGA) and non-uniform ADC is implemented to suppress interference and avoid saturation of signal chain. While drawing 35 mA current, this receiver achieves a total noise figure of 4 dB and a maximum gain of 105 dB, with a die area of 2.4 9 2.4 mm 2 .
A new Ag(i)-based HE-MOFs exhibited a compact 3D structure with channels containing coordinated NO3− and CH3COO− ions. The superior density, thermostability, insensitiveness and detonation properties indicated it can be used as potential explosive.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
