RF Modeling of 45nm Low-Power CMOS Technology

Wang J., Li H., Pan L.H., Gogineni U., Groves R., Jagannathan B., Na M-H, Tonti W., Wachnik R., IBM Semiconductor Research and Development Center, US

As CMOS has grown to be one of the principle technologies for RF IC design, accurate modeling of MOSFETs at high frequencies becomes increasingly important. In this paper, we present an advanced RF modeling work [...]

Elements of Statistical SPICE Models

Lu N., Watts J., Springer S.K., IBM, US

We discuss several elements of statistical SPICE models and present our solutions. We present (i) a solution of automatically detecting Monte Carlo vs. skewed simulations, (ii) a method of modeling an arbitrarily given asymmetric or [...]

A Scalable POWER MOSFET Model with an Integrated Body-Diode Including Reverse Recovery

Luo Z., Hall J., Xiao Y., Young A., Carroll R., Connerney D., Fairchild Semiconductor, US

Traditional high-voltage MOSFET models include parasitic source-bulk and drain-bulk diode models. However, these models are simplified diode models and lack some of the more detailed aspects of p-n junctions diodes such as breakdown voltage, advanced [...]

Compare and Contrast HiSIM-LDMOS and BSIM based compact model of High Voltage MOSFETs for Analog Applications

Young A., Hall J., Luo Z., Xiao Y., Connerney D., Fairchild Semiconductor, US

A pair of scalable spectre models, one utilizes the Surface Potential based HiSIM-LDMOS model, and the other, the conventional Vth-based BSIM3v3 model, were extracted based on a test vehicle designed with both Drain-Extended CMOS and [...]

What is a Transistor?

Sah C., Jie B., University of Florida, US

After 75 years of learning vacuum tube and solid state electronics in three human generations, we now come to the end of the complete understanding of what is a transistor. It is far beyond, eight [...]

Effects of Memories of Polarization Interactions during Particle Transport Induced by One Gradient AC Electric Field

Shen Y., Tada S., Qiu Z., The City College of the City University of New York and New York Center for Biomedical Engineering, US

On the Nanotech 2008 in Boston, we reported our experimental observations of the particle instability and island-like structures in the suspension of poly alpha olefin particles and corn oil when the suspension was exposed to [...]

Particle Transport in Magnetophoretic Microsystems

Furlani E.P., University at Buffalo, US

Magnetophoretic microsystems are finding increasing use in biotechnology and biomedicine for applications such as bioseparation and immuno-assays. These microfluidic systems typically contain embedded elements that produce a magnetic field distribution within a microchannel. This applied [...]

A Solid Electrolyte Valve for Micro/Nano-fluidics

Yang Y., Zhang X., Kozicki M.N., Chae J., Arizona State University, US

This paper describes recent work on a valve to regulate liquid flow in micro/nano-fluidic channels using electrodeposited nanostructures on a solid-state AgGeSe electrolyte. The valve utilizes the extremely rough surface morphology of the electrodeposits to [...]

Analysis of an Electrostatically Actuated MEMS Drop Ejector

Furlani E.P., Eastman Kodak Company, US

MEMS are finding increasing use for applications that require the controlled generation and delivery of picoliter-sized droplets. Common applications include biomedical and biochemical microdispensing and most notably, ink jet printing. Micro-droplets can be produced as [...]

Design Simulations of a Micropump with Multiple Actuating Mechanisms

Koombua K., Pidaparti R.M., Virginia Commonwealth University, US

This paper presented the design simulations of a valveless micropump with novel multiple vibrating membranes as actuators and investigated its performance characteristics. The designed PDMS micropump consists of three nozzle/diffuser elements with vibrating membranes that [...]
