Modeling Surface Recombination with Enhanced Devices Network for Optoelectronics

Jean-Michel Sallese, Camillo Stefanucci, Pietro Buccella, Chiara Rossi

We present a lumped devices network approach to simulate surface recombination effects in optoelectronics devices. The network is composed of generalized lumped devices where the excess carrier concentrations and gradients are mapped on electrical quantiti ...

Area and Power Efficient Ultra-Wideband Transmitter Based on Active Inductor

Catherine Dehollain, Kerim Türe, Arnout Jan J Devos, Franco Maloberti

This paper presents the design of an impulse radio ultra-wideband (IR-UWB) transmitter for low-power, short-range, and high-data rate applications such as high density neural recording interfaces. The IR-UWB transmitter pulses are generated by modulating t ...

Multi-degree-of-freedom low-frequency electroacoustic absorbers through coupled resonators

Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Sami Driss Karkar

Electroacoustic absorbers represent an interesting solution for low-frequency sound absorption in rooms. These systems simply consist of closed-box electrodynamic loudspeakers, whose acoustic impedance at the diaphragm is judiciously adjusted by connecting ...

Charge-Based Distortion Analysis of Nanoscale MOSFETs

Christian Enz, Francesco Chicco, Alessandro Pezzotta

This paper presents a study of MOSFETs' linearity, exploiting a simplified version of the charge-based EKV model. It allows to deduce analytically the one-tone and two-tone harmonic distortions introduced by the nonlinear ID-VG MOSFET characteristic as a f ...

Interfacing Qubits via Cryo-CMOS Front Ends

Edoardo Charbon, Andrea Ruffino, Yatao Peng

This work describes a basic interface between solid-state quantum bits (qubits) and classical environments. We describe a multiplexer, a circulator, and a low noise amplifier, designed for cryogenic temperature operation in a 40 nm CMOS technology node. Th ...

Nonlinear graphene quantum capacitors for electro-optics

Sina Khorasani, Akshay Koottandavida

Owing to its peculiar energy dispersion, the quantum capacitance property of graphene can be exploited in a two- dimensional layered capacitor configuration. Using graphene and boron nitride, respectively, as the electrodes and the insulating dielectric, a ...

Finite strain FFT-based non-linear solvers made simple

Thomas Willem Jan de Geus

Computational micromechanics and homogenization require the solution of the mechanical equilibrium of a periodic cell that comprises a (generally complex) microstructure. Techniques that apply the Fast Fourier Transform have attracted much attention as the ...
