The low accuracy rates of text–shape dividers for digital ink diagrams are hindering their use in real world applications. While recognition of handwriting is well advanced and there have been many recognition approaches proposed for hand drawn sketches, there has been less attention on the division of text and drawing ink. Feature based recognition is a common approach for text–shape division....

In this paper, different topologies of dual-frequency modified 3-way Bagley polygon power dividers are designed and analyzed. Equal split power division is achieved at arbitrary design frequencies. In the first structure, two-section transmission line transformer is used to realize the dual-frequency operation. In the second and third structures, dual-frequency T-shaped and π-shaped matching ne...

In this paper, the research advances in SIW-like (Substrate Integrated Waveguide-like) guided wave structures and their applications in the State Key Laboratory of Millimeter Waves of China is reviewed. Our work is concerned with the investigations on the propagation characteristics of SIW, half-mode SIW (HMSIW) and the folded HMSIW (FHMSIW) as well as their applications in microwave and millim...

Hardware dividers are needed in many areas of applications like computer floating-point units, communication systems, cryptography, signal processing, etc. The performance requirements of these applications differ regarding data and architectural issues. In this paper, the basic principles used in hardware integer dividers are shown. A hybrid data-dependent divider is proposed based on several ...

This paper presents a low power, low jitter, PVTstable film-bulk acoustic wave resonator (FBAR) based all digital phase-locked loop (ADPLL) in a 65nm CMOS process. We introduce a power-efficient integer-N ADPLL architecture, where the digitally-controlled FBAR oscillator (FBAR DCO) achieves phase-lock to a reference clock without any explicit frequency dividers in the feedback path. The simplif...

In Electron cyclotron resonance heating systems, high-power multiplexers can be employed as power combiners, adjustable power dividers, fast switches to toggle the power between two launchers, as well as frequency sensitive directional couplers to combine heating and diagnostic applications on one launcher. In the paper, various diplexer designs for quasi-optical and corrugated waveguide transm...

The successful design and measurement of high-performance coplanar waveguide (CPW) quadrature hybrid couplers integrated in MCM-D at Ku and Ka-band and Wilkinson power dividers at X-band are discussed in this work. The authors have investigated the feasibility of integrating 3-dB quadrature couplers in the MCM-D technology. Quadrature couplers based on two edge-coupled lines are not practical, ...
