Electrical Modeling of Long-Wavelength VCSELs for Intrinsic Parameters Extraction

Elyahou Kapon, Vladimir Iakovlev

We present an efficient method to model the small-signal modulation response of a long-wavelength VCSEL chip using an equivalent electrical circuit. This circuit serves two distinct purposes. Based on T-Matrix formalism, it is used to remove the parasitics ...

Improving the power-delay performance in subthreshold source-coupled logic circuits

Seyed Armin Tajalli, Yusuf Leblebici

Subthreshold source-coupled logic (STSCL) circuits can be used in design of low-voltage and ultra-low power digital systems. This article introduces and analyzes new techniques for implementing complex digital systems using STSCL gates with an improved pow ...

Self-Organizing Configurable Bit Slice Processors

Joël Rossier

Living organisms are endowed with three structural principles: multicellular architecture, cellular division, and cellular differentiation. Implemented in digital according to these principles, our bit slice processors present self-organizing mechanisms li ...

Self-replication of complex digital circuits in programmable logic devices

Joël Rossier

Nature is an incredibly complex system resulting from the interactions of many different interdependent species, composed of many individual organisms, which are in turn composed of an extremely large number of cells. In multi-cellular organisms, the paral ...

Asynchronous front-end asic for x-ray medical imaging applications implemented in CMOS 0.18μm technology

Rafal Tomasz Dlugosz

An idea as well as a CMOS implementation of the novel multi-channel readout front-end ASIC for nuclear X-ray imaging system has been presented in the paper. The circuit has been designed in an example configuration with eight equal channels, but the modula ...

A low-power 2.4 GHz CMOS receiver using BAW resonators

Jérémie Chabloz

It has already been a few years since the first appearance of micro-electromechanical systems (MEMS) in academic research. Since then, a broad number of devices have been designed under this generic term. Bulk-acoustic wave (BAW) resonators are among the f ...

Tri-State Buffer/Bus Driver Circuits in MOS Current-Mode Logic

Yusuf Leblebici, Stéphane Badel

In this paper, two circuits are proposed to implement tri-state buffers/bus drivers for MOS Current-Mode Logic digital circuits. The first is a switch-based, fully differential circuit, while the second is a voltage follower-based, pseudodifferential circu ...

Analog Genetic Encoding for the Evolution of Circuits and Networks

Dario Floreano, Claudio Mattiussi

This paper describes a new kind of genetic representation called analog genetic encoding (AGE). The representation is aimed at the evolutionary synthesis and reverse engineering of circuits and networks such as analog electronic circuits, neural networks, ...

Bio-inspired cellular machines

Fabien Vannel

Information technology has only been around for about fifty years. Although the beginnings of automatic calculation date from as early as the 17th century (W. Schickard built the first mechanical calculator in 1623), it took the invention of the transistor ...
