Synchronous and Asynchronous Detection of Ultra-Low Light Levels

Peter Seitz, Christian Lotto

Comprehensive analysis of noise sources in photocharge detectors leads to two novel, compact pixel circuits for ultra-low-noise light detection using optimum bandwidth engineering. A synchronous 4T CMOS image sensor pixel with in-pixel amplification reache ...

Some observations on limited feedback for multiaccess channels

Michael Christoph Gastpar

Most information-theoretic analyses of communication systems with feedback assume perfect output feedback. For multiaccess channels, this feedback can enable cooperation between users. However, as shown by a simple example, the rate required by the feedbac ...

Data-driven methods for tracking improvement

Mark Edward John Butcher

The tracking precision required by modern industrial applications is continuously increasing. Feedback control alone is often no longer capable of giving the necessary tracking accuracy and so the use of two-degree-of-freedom controllers, which include a f ...

Self-sustained low power oscillator based on vibrating body field effect transistor

Mihai Adrian Ionescu, Daniel Grogg, Suat Ayoz

The operation of a vibrating body field effect transistor (VB-FET) near pull-in is exploited to experimentally demonstrate a self-oscillating device. The positive feedback mechanism is triggered at the onset of inversion in a depleted VB-FET channel, near ...

Shunt loudspeaker techniques for use as liners for engine nacelles

Hervé Lissek

In this paper, the liner concept is an electroacoustic transducer which acoustic impedance can be changed by electrical means, be it passive or active. Among the different ways to obtain variable acoustic properties on an electroacoustic transducer's voici ...

Er-Yb waveguide amplifiers in novel silicate glasses

Jana Jágerská

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 ...

Noise and small-signal modeling of nanoscale MOSFETs

Ananda Sankar Roy

After years of intensive research effort, the design of RF integrated circuits in CMOS has now reached a wide acceptance for industrial designs. This is due to the high unity gain frequency and low-noise performance of today's deep sub micrometer MOS trans ...

Data-Driven Estimation of the Infinity Norm of a Dynamical System

Dominique Bonvin, Alireza Karimi, Klaske van Heusden

The estimation of a system’s infinity norm using one set of measured input and output data is investigated. It is known that, if the data set is noise free, this problem can be solved using convex optimization. In the presence of noise, convergence of this ...

Noise Modeling in Lateral Nonuniform MOSFET

Christian Enz, Jean-Michel Sallese, Ananda Sankar Roy

In this paper, we present an analytical noise modeling methodology for lateral nonuniform MOSFET. We demonstrate that the noise properties of lateral nonuniform MOSFETs are considerably different from the prediction obtained with the conventional Klaassen- ...
