Phase noise, of a designed and realized test oscillator, as a consequence of low frequency (LF) noise up-conversion was simulated. The analysis shows that low frequency noise sources, which are inside the oscillator transistor, give the pure Gaussian distribution of phase noise and LF noise sources located outwith the transistor change this distribution. This behavior could be explained by the influence of the transistor and the transistor's package impedance, which contribute to the signal delay. The microwave test oscillator is designed and realized with AlGaAs/InGaAs HEMTs.","PeriodicalId":221518,"journal":{"name":"2002 23rd International Conference on Microelectronics. Proceedings (Cat.

Here we compare the performance of a new IMC Hall sensor ASIC with the performance of traditional magnetic field sensors, such as AMR, GMR, and conventional Hall sensor ASICs. We find that the detectivities of AMRs and GMRs for AC magnetic fields are much better than those of Hall ASICs; for low-frequency fields, the performance gap is smaller; but for DC fields, the resolution of the IMC Hall ASIC is much better than that of GMRs and approaches the resolution of a nonswitched AMR. Also according other parameters, the IMC Hall ASIC is positioned in the gap between AMRs, GMRs, and the conventional Hall ASIC magnetic field sensors.","PeriodicalId":221518,"journal":{"name":"2002 23rd International Conference on Microelectronics.

The surfaces of these samples were modified using long exposure to the atmosphere (series A), etching by 0.5% Br-methanol during 1 minute (series B) and during 5 minutes (series C). For each series samples PL spectra were measured at different temperatures in the range from 16 to 300 K. PL bands at about 2.1 eV and 2.3 eV are recognized in PL spectra of each series samples. The analysis of PL and Raman spectra shows that the band at /spl sim/2.1 eV is caused by presence of the nonstoichiometric oxides. The band at 2.3 eV originates of organic compounds which are deposited at the surface during etching process. PL of the observed samples decreases after irradiation by intense nanosecond pulse of Nd:YAG laser.","PeriodicalId":221518,"journal":{"name":"2002 23rd International Conference on Microelectronics.
