On-chip transmission line modelling and design become increasingly important as frequencies are continuously going up. This paper explores possibilities to implement transmission lines on CMOS ICs via coupled coplanar strips. EM-field simulations with SONNET are used to estimate important transmission line properties like characteristic impedance, propagation velocity and loss in a 0.18 micron ...

In recent years, high-speed wireless communication is in vogue. In wireless communication systems, multipath fading, delay and interferenc occurres by reflection or diffraction. In a high-speed wireless communication, it becomes a necessary to separate desired signal from delay or interference signal. Thus to overcome these problems Smart antenna systems have been developed. Basically there are...

This paper presents the application of a connectionist control-learning system to autonomous mini-robots. These robots are specially designed and equipped for learning easily deened yet challenging control tasks. The system must learn despite noisy, low-grain sensory input and uncertain interactions between motor commands and eeects in the world. The system's design is severely constrained by t...

In this paper we introduce the notions of uniformly quasi-primary ideals and uniformly classical quasi-primary submodules that generalize the concepts of uniformly primary ideals and uniformly classical primary submodules; respectively. Several characterizations of classical quasi-primary and uniformly classical quasi-primary submodules are given. Then we investigate for a ring $R$, when any fi...

The Marchand balun has larger bandwidth than other types of combiners and has been used extensively since its introduction. The Marchand balun has also been extensively used in planar systems in both broadside-coupled and edged-coupled configurations. This paper describes the design and development of two microstrip, folded, edge-coupled Marchand baluns for use as anti-phase power combiner. The...
