Abstract: The analysis of transversal filters based on a novel cell design in common-source configuration (TF-CS) is presented. Based on this approach, a distributed transversal filter was designed as a monolithic microwave integrated circuit (MMIC) for optical-CDMA receiver systems [1]. In order to assess its performance, a transversal filter based on Gilbert cells (TF-GC) was designed using t...

The purpose of this paper is to present a methodology for the evaluation of the Defect Level in an IC design environment. The methodology is based on the extension of Williams-Brown formula to non equiprobable faults, which are collected from the IC layout, using the information on a typical IC process line defect statistics. The concept of weighted fault coverage is introduced, and the Defect ...

Formal Synthesis is a methodology developed at Kent for combining circuit design and veriication. We have reinterpreted this methodology in Isabelle's theory of higher-order logic so that circuits are synthesized using higher-order resolution. Our interpretation sim-pliies and extends Formal Synthesis both conceptually and in implementation. It also supports integration of this development styl...

Present-day photonic terahertz (100 GHz–10 THz) systems offer dynamic ranges beyond 100 dB and frequency coverage 4 THz. They yet predominantly employ free-space Terahertz propagation, lacking integration depth miniaturisation capabilities without sacrificing their extreme coverage. In this work, we present a high resistivity silicon-on-insulator-based multimodal waveguide topology including ac...

Until now only cursory descriptions of mathematical models for defect sensitivities of integrated circuit chips have been given in the yield literature. This paper treats the fundamentals of the defect models that have been used successfully at IBM for a period of more thanjifteen years. The effects of very small defects are discussedjirst. The case of photolithographic defects, which are of th...

The history of micro system electronics is briefly traced through the successive stages of: miniaturization; subminiaturization; microminiaturization; thin-film integrated circuits; semiconductor integrated circuits; and finally morphological integrated circuits or functional blocks. The term integrated circuit is defined as the combination, on or within a single chunk of material, of multiple ...

The demand for increasing speed and low power dissipation triggers numerous research efforts with the increasing demand of wireless portable communication systems in underground mines driven by batteries. Presence of highly flammable gases in underground mines prohibits the use of higher power dissipating electronic systems. Low power wireless portable communication devices can safeguard the li...

Trustworthy system development entails a high nonrecurring engineering (NRE) cost together with a low volume of units over which to amortize that cost. For example, the potential for developmental and operational attacks against hardware requires countermeasures that make it very expensive to design and manufacture custom hardware used to build high assurance systems. To address these problems,...

Our analog and mixed-signal VLSI course uses two hardware labs. The mirrors lab demonstrates the effects of mismatch and oxide encroachment on transistors and current mirrors. The students experiment with individual transistors and three different sets of mirror circuits to obtain a handson experience with some of the limitations of integrated circuit processing. The chip has been fabricated us...
