To encourage continued investments in R&D to result in technological advancements in the field of microelectronics, protection of Intellectual Property Rights (IPR) embedded in the layout designs is a very important issue. In Thailand, protection is provided for the layout design of integrated circuits through the Protection of Layout-Designs of Integrated Circuits Act, B.E. 2543 (2000). The la...

in this article, we suggested a novel design of polarization splitter based on coupler waveguide on inp substrate at 1.55mm wavelength. photonic crystal structure is consisted of two dimensional (2d) air holes embedded in inp/ingaasp material with an effective refractive index of 3.2634 which is arranged in a hexagonal lattice. the photonic band gap (pbg) of this structure is determined using t...

The development of numerical techniques now permits us to analyze complex structures such as dielectric resonator filters and planar passive elements for coplanar monolithic microwave integrated circuits. In this paper, we describe a novel method for designing dielectric resonator filters. Then a Chebychev band pass filter is designed by coaxially placing high-Q TM01Q dielectric resonators ...

A historical sketch of microwave integrated circuits, monolithic microwave integrated circuits, and their application is presented in this paper.

Monolithic integrated millimeter-wave circuits based on silicon and SiGe are emerging as an attractive option in the field of millimeter-wave communications and millimeterwave sensorics. The combination of active devices with passive planar structures, including also antenna elements, allows single-chip realizations of complete millimeter-wave front-ends. This paper reviews the state-of-the-art...

The microstrip line is widely used as the planar transmission line in microwave integrated circuits and high speed interconnecting buses. In this paper, we use COMSOL multiphysics to study multiconductor microstrip systems on microwave integrated circuits. We specifically illustrate the modeling of open four and five conductors systems. We successfully demonstrated the calculation of the capaci...

Due to the lack of a secure supply chain, it is not possible to fully trust the integrity of electronic devices. Current methods of verifying integrated circuits are either destructive or non-specific. Here we expand upon prior work, in which we proposed a novel method of reverse engineering the finite state machines that integrated circuits are built upon in a non-destructive and highly specif...
