This paper presents an effective decoupling strategy to reduce radio frequency interference (RFI) noise from power plane of double data-rate (DDR) memory. Dual-referencing routing with both power and ground plane is widely used in DDR memory but prone to RFI radiation. Simulations are conducted to show a) self-resonance of capacitor significantly enhances effectiveness of decoupling, b) impedance...
Black phosphorus (BP) has been proposed as the channel material in the next generation ultrascaled CMOS devices. In order to gain insight into the current characteristics in 2-D layered materials, the current distribution of a few-layer BP Schottky barrier FET is investigated via state-of-the-art quantum device simulations. Approximately 40% of the total current was found to be concentrated in the...
Two types of polymer waveguides made by dry film process are characterized for silicon photonics chip packaging. In this paper, both DC and high-speed performance of the waveguides are demonstrated. DC characterization includes coupling loss from/to a single-mode fiber (SMF), near field pattern (NFP), far field pattern (FFP), and alignment tolerance measurement. The designed values for the waveguide...
A novel RF-MEMS structure to achieve tunable bandwidth is presented in this paper. A movable nickel electrode is employed to realize tunable broad-side coupling. The bottom electrode is fabricated with high resistivity-SiCr to avoid performance degradation. This tunable coupling section is implemented in a planar MEMS tunable filter that consists of λ/2 coplanar waveguide (CPW) resonators...
