This paper presents results from the numerical investigation of nonlinear feedback interactions between ULF field-aligned currents (FACs) and ionospheric plasma in global magnetospheric resonator with a non-symmetrical distribution density conjugate hemispheres. The asymmetry is enhanced by introduction valley hemisphere where already lower. main result this study that resonator, mechanism, dri...

We present a simple and efficient method for the extraction of thermal channel noise of MOS FET’s in quarter and sub-quarter micron technologies from NF50 (noise figure at 50 Ohm source resistance) measurements. For shorter channel lengths the experimental results shows a continuously rising deviation from the classical long channel theory [1]. For a 0.18 μm technology a γ≈6 instead of 2/3 in s...
