Er-Yb waveguide amplifiers in novel silicate glasses

A set of novel silicate glasses containing ZnO and co-doped with Er3+ and Yb3+ was designed as substrates for optical waveguide amplifiers. Characterized by exceptionally low up-conversion, minimum Er concentration quenching and high mechanical as well as ...

Impairments in Gain-Equalized Distributed Fiber Raman Amplifiers due to Four-Wave Mixing and Parametric Amplification Processes

Marcelo Alfonso Soto Hernandez

In this work, by means of numerical simulations, we verify that four‐wave mixing (FWM) processes, including depletion and parametric gain, generate a redistribution of pump power in distributed fiber Raman amplifiers (DFRAs). As a consequence of pump‐pump ...

Current Sensing Completion Detection for Subthreshold Asynchronous Circuits

Eric Vittoz, Yusuf Leblebici, Omer Can Akgun

In this paper a novel completion detection method for self-timed, asynchronous subthreshold circuits is presented. By employing the self-timed operation principle, substantial speed gains in the operation of the asynchronous pipelines can be realized. The ...

A Power-Efficient LVDS Driver Circuit in 0.18-um CMOS Technology

Seyed Armin Tajalli, Yusuf Leblebici

This article presents a power-efficient and low-voltage CMOS output driver circuit based on low-voltage differential signaling (LVDS) standard. To reduce the ringing at the output of the proposed driver circuit and simultaneously keep the power consumption ...

Hall sensor and method of operating a Hall sensor

Giovanni Boero, Radivoje Popovic, Pavel Kejik, Predrag Drljaca

A Hall sensor comprises a Hall element (1; 30; 31; 60) and an amplifier (2; 32; 33). The Hall element is placed inside the amplifier so that the current flowing through the Hall element also flows through the transistors of an amplifier stage of the amplif ...

Characterization of a thick layer a-Si : H pixel detector with TFA technology using a scanning electron microscope

Christophe Ballif, Arvind Shah, Sylvain Dunand, Matthieu Despeisse

The electron beam induced current (EBIC) technique was used to characterize a 32 μm thick hydrogenated amorphous silicon n-i-p diode deposited on top of an ASIC, containing several channels of active feedback pre-amplifiers (AFP) with peaking time of 5 ns. ...

Ammonia trace measurements at ppb level based on near-IR photoacoustic spectroscopy

Luc Thévenaz, Jean-Philippe Besson

A photoacoustic sensor using a laser diode emitting near 1532 nm in combination with an erbium-doped fibre amplifier has been developed for ammonia trace gas analysis at atmospheric pressure. NH3 concentration measurements down to 6 ppb and a noise-equival ...
