In this paper, a 60 GHz complementary metal-oxide-semiconductor (CMOS) balun low-noise amplifier (LNA) was implemented for millimeter-wave communication. To improve the gain and noise performance, slow-wave coplanar waveguides (S-CPW) with high quali

A wideband common-gate CMOS low noise amplifier with negative resistance technique is proposed. A novel single-ended negative resistance structure is employed to improve gain and noise of the LNA. The inductor resonating is adopted at the input stage

A heteroepitaxial growth model of the ZnO film on sapphire(0001) is calculated by using a plane wave ultrasoft pseudo-potential method based on the density functional theory. A strong chemical adsorption on the sapphire(0001) is observed. It is found

The adsorption and the growth of ZnO on α- Al 2 O 3(0001) surface at various temperatures are theoretically calculated by using a plane wave pseudopotentials (USP) method based on density functional theory. The average adsorption energy of ZnO at 40
