Micromachining techniques are being increasingly used to develop miniaturized sensor and actuator systems. These system designs tend to be captured as layout, requiring extraction of the equivalent microelectromechanical circuit as a necessary step for design verification. This paper presents an extraction methodology to (re-)construct a circuit schematic representation from the layout, enablin...

In this paper, an accurate and simple small signal model of RF MOSFETs accounting for the distributed gate effect, the substrate parasitics and charge conservation is proposed. Meanwhile, a direct and accurate extraction method using linear regression approach for the components of the equivalent circuit of the MOSFET with S-parameters analysis is also proposed.

This paper focuses on the extraction of an accurate small-signal equivalent circuit for metal-oxide-semiconductor field-effect transistors (MOSFETs). An analytical modeling approach was developed and successfully validated through the comparison between measured and simulated scattering parameters. The extraction of the equivalent circuit elements allowed for the estimation of the intrinsic uni...

This paper describes verification techniques that have been implemented as part of an interactive symbolic IC des ign system. Circuit analysis programs perform node extraction and gate decomposition. They generate both transistor and gate level circuit desriptions which are used as input to a transistor level digital MOS timing s imulator. The extraction programs make use of an intermediate cir...

This paper presents a systematic parameter extraction method for an HBT temperature-dependant equivalent-circuit DC model. A reliable procedure was developed for determining the HBT thermal resistance, requiring only forward Gummel data at different temperatures and collector-emitter bias voltages. The extraction method was applied to predict the DC characteristics of a 2x25 μm emitter-area InG...

spike sorting is a class of techniques used in the analysis of electrophysiological data. studying the dynamics of neural activity via electrical recording relies on the ability to detect and sort neural spikes recorded from a number of neurons by the same electrode. this article reviews methods for detecting and classifying action potentials, a problem commonly referred to as spike sorting.
