Ultra Low Voltage Synthesizable Memories: A Trade-Off Discussion in 65 nm CMOS

Andreas Peter Burg, Pascal Andreas Meinerzhagen, Oskar Andersson

In this study, design considerations for ultra low voltage (ULV) standard-cell based memories (SCM) are presented. Trade-offs for area cost, leakage power, access time, and access energy are discussed and realized using different read logic styles, latch a ...

Synthesis, Morphological, and Electro-optical Characterizations of Metal/Semiconductor Nanowire Heterostructures

Anna Fontcuberta i Morral, Heidi Andrea Potts, Sonia Conesa Boj

In this letter, we demonstrate the formation of unique Ga/GaAs/Si nanowire heterostructures, which were successfully implemented in nanoscale light-emitting devices with visible room temperature electroluminescence. Based on our recent approach for the int ...

Exploiting Circuit Duality to Speed Up SAT

Giovanni De Micheli, Pierre-Emmanuel Julien Marc Gaillardon, Luca Gaetano Amarù

In this paper, we establish a non-trivial duality between tautology and contradiction check to speed up circuit SAT. Tautology check determines if a logic circuit is true in every possible interpretation. Analogously, contradiction check dete ...

Modeling Minority Carriers Related Capacitive Effects for Transient Substrate Currents in Smart Power ICs

Maher Kayal, Jean-Michel Sallese, Camillo Stefanucci, Pietro Buccella

This paper presents an extended model for transient and ac circuit-level simulation of minority carriers propagation through the substrate of smart power integrated circuits (ICs). A p-n junction and a diffusion resistor with capacitive components are prop ...

Modeling Parasitic Vertical PNP in HVCMOS

Maher Kayal, Jean-Michel Sallese, Camillo Stefanucci, Pietro Buccella

High voltage CMOS active devices inherently have a parasitic vertical bipolar transistor. The parasitic PNP structure can be activated during high-power switching operation causing a potential shift of the substrate. In this work a spice-modeling approach ...

A charge carrier transport model for donor-acceptor blend layers

Wolfgang Richard Tress

Highly efficient organic solar cells typically comprise donor-acceptor blend layers facilitating effective splitting of excitons. However, the charge carrier mobility in the blends can be substantially smaller than in neat materials, hampering the device p ...

Shallow donor and deep DX-like center in InAlN layers nearly lattice-matched to GaN

Nicolas Grandjean, Jean-François Carlin, Marcel Py, Lorenzo Lugani

Nonintentionally doped 200-nm-thick In0.16Al0.84N/n(+)-GaN samples were grown by metal-organic vapor phase epitaxy and used for the electrical characterization of InAlN. In the temperature range 180-400 K, the forward current of Schottky diodes is dominate ...
