A new approach for power combining several low-voltage CMOS amplifiers using a new on-chip transmission line transformer structure is presented. The power combiner utilises the interconnection of short sections of integrated differential lines and has an efficiency independent of the transformation ratio. Full-wave electromagnetic simulation confirms the operation and low insertion loss of the ...

A hexachiral honeycomb structure with good mechanical properties, is investigated through full wave electromagnetic simulation. This new material shows some interesting EMC properties and promises better performance using different insertion techniques. The effect of the electromagnetic chirality is investigated. Design maps and thermal computations are derived.

Precision rectifiers are important building blocks for analog signal processing. The traditional approach based on diodes and operational amplifiers (OpAmps) exhibits undesirable effects caused by limited OpAmp slew rate and diode commutations. In the paper, a full-wave rectifier based on one CDTA and two Schottky diodes is presented. The PSpice simulation results are included.

A full-spectral third-generation ocean wind-wave model, Wavewatch-III, has been implemented in the South China Sea (SCS) for investigating wind-wave characteristics. This model was developed at the Ocean Modeling Branch of the National Centers for Environmental Prediction (NCEP). The NASA QuickSCAT data (0.258 resolution) 2 times daily were used to simulate the wind waves for the entire year of...

in this paper the telemac-3d model has been hired to simulate and study the high waves’ interaction with coastal structures. therefore a special arrangement of telemac-3d has been prepared in this study to simulate wave generation, coastal processes, wave set-up and overtopping over coastal structures. experimental data has been used to verify this arrangement of the model. thereafter, the mode...

The results of a recent effort to compare the sky noise power received by broadband dipole antennas at LWA frequencies as predicted by simulation and given by measurement are summarized. The simulation method, which combines results from a full-wave simulation of a given antenna design with a properly frequency-scaled all-sky map of radio continuum to generate predicted drift scans is first des...
