An improved small-sized filter is presented for ultra-wideband (UWB) systems. The filter comprises an only one-cell composite right and left handed-transmission line (CRLH-TL) resonator, step impedance (SI), and two spurlines. The one-cell CRLH-TL resonator has a small area and a wide passband. An SI is used to suppress the harmonics of the passband. And the two spurlines nestle the one-cell CRLH-TL...
A novel single crystalline silicon diamond-shaped atomic force microscope (AFM) cantilever for accurate mechanical tests of MEMS structures is presented. A strip bending test of micromachined gold thin film strip specimens has been performed using the proposed AFM cantilever. The experimental results show that a more accurate and uniform bending test is possible with this new cantilever by suppressing...
A novel stress-anneal approach has been investigated to separate the role of electrons and hole charge trappings in Hf-based gate oxides. It is observed that heat treatment following a stress experiments on Hf-based MOSFET can effectively eliminate electron trapping in the oxide. We also report that hole accumulation in the bulk of the Hf-based dielectrics is primarily responsible for dielectric breakdown,...
