The effects of emitter degeneration on the oscillation frequency, output noise and tuning range of an emitter degenerated LC oscillator designed using bipolar transistors (BJT) is analyzed. Simulation results show increased oscillation frequency, tuning range and carrier-to-noise ratio (CNR). Design guidelines for emitter degenerated LC oscillators are also given.

One approach to super-resolution fluorescence microscopy, termed stochastic localization microscopy, relies on the nanometer scale spatial localization of individual fluorescent emitters that stochastically label specific features of the specimen. The precision of emitter localization is an important determinant of the resulting image resolution but is insufficient to specify how well the deriv...

GaInP/GaAs Heterojunction Bipolar Transistors(HBTs) offer significant advantages over AlGaAs/GaAs devices such as large valence band discontinuity and excellent etching selectivity as demonstrated by the authors[1] and other laboratories. Excellent microwave properties have been obtained using GaInP HBT[2] and Chemical Beam Epitaxy(CBE) using TBA/TBP precursors has been reported for material gr...

A hybrid white organic light-emitting diode (WOLED) with an external quantum efficiency above 20% was developed using a new blue thermally activated delayed fluorescent material, 4,6-di(9H-carbazol-9-yl)isophthalonitrile (DCzIPN), both as a blue emitter and a host for a yellow phosphorescent emitter. DCzIPN showed high quantum efficiency of 16.4% as a blue emitter and 24.9% as a host for a yell...

Biofouling has been identified as a major contributor to emitter clogging in drip irrigation systems that distribute reclaimed wastewater. Two types of drip emitters were evaluated for use with reclaimed wastewater. Microbial biofilm accumulations, including proteins, polysaccharides, and phospholipid fatty acids (PLFAs), were tested to determine the biofilm development and diversity in the emi...

Wedevelop awavefunction approach to describe the scattering of two photons on a quantum emitter embedded in a one-dimensional waveguide. Ourmethod allows us to calculate the exact dynamics of the complete system at all times, as well as the transmission properties of the emitter.We show that the nonlinearity of the emitter with respect to incoming photons depends strongly on the emitter excitat...

water crisis is one of the basic problems in the arid and drought prone areas like iran. this condition in the recent years has aggravated due to drought phenomenon. thus, using poor water quality has increased in areas where good quality is not available. in this study, in order to investigate clogging, 5 types of emitters including micro flapper, netafim, corona, axios and iran drip were test...

DNA microarray analyses were used to investigate the effect of cell-incorporated 35S-methionine on human colorectal carcinoma cells. This beta-radiation-induced gene expression profile was compared with that induced by external gamma-radiation. The extent of DNA fragmentation was used as a biomarker to determine the external gamma dose that was bioequivalent to that received by cells incubated ...

A new photocathode called a ‘‘photosensitive field emitter’’ has been proposed, and a prototype was fabricated. This new Ž . photocathode was realized using a gated Si field emitter tip and an hydrogenated amorphous Si a-Si:H p–i–n photodiode. The emission current from the photocathode is proportional to the illumination intensity, and detectable maximum of the illumination intensity was about ...
