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 ...

Influence of shot noise on phase measurement accuracy in digital holographic microscopy

Christian Depeursinge, Tristan Colomb, Benjamin Rappaz, Pierre Marquet, Jonas Kühn, Florian Charrière

Digital Holographic Microscopy (DHM) is a single shot interferometric technique, which provides quantitative phase images with subwavelength axial accuracy. A short hologram acquisition time (down to microseconds), allows DHM to offer a reduced sensitivity ...

In this Letter, it is shown that global, nonlinear, particle-in-cell (PIC) simulations of electron temperature driven turbulence recover the same level of transport as flux-tube codes when the level of statistical noise, associated with the PIC discretizat ...

Shot noise perturbations in digital holographic microscopy phase images

Christian Depeursinge, Etienne Cuche, Frédéric Montfort, Florian Charrière

In digital holographic microscopy, shot noise is an intrinsic part of the recording process with a digital camera. We present a study based on simulations describing how shot noise influences the quality of the reconstructed phase images under different be ...

Shot noise influence in reconstructed phase image SNR in digital holographic microscopy

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Pierre Marquet, Florian Charrière

In digital holographic microscopy, shot noise is an intrinsic part of the recording process with the digital camera. We present a study based on simulations and real measurements describing the shot-noise influence in the quality of the reconstructed phase ...

We present a shot noise based model for a large family of ultrawide bandwidth (UWB) signals. These include time-hopping and direct-sequence signaling with pulse position, interval, and amplitude modulations. Each specific signal is constructed by adding fe ...

In this correspondence, we consider sampling continuous-time periodic bandlimited signals which contain additive shot noise. The classical sampling scheme does not perfectly recover these particular nonbandlimited signals but only reconstructs a lowpass fi ...

Shot noise influence in reconstructed phase images SNR in digital holographic microscopy

Christian Depeursinge, Etienne Cuche, Pierre Marquet, Florian Charrière

We present a study based on simulations describing how shot noise, an intrinsic part of the recording process with a digital camera, influences the quality of the reconstructed phase images under different beams intensities configurations. ...

UWB Signals as Shot Noises

Andrea Ridolfi

We present a shot-noise based model for a large family of ultrawide bandwidth (UWB) signals. These include time-hopping and direct-sequence signaling with pulse position, interval and amplitude modulations. Each specific signal is constructed by adding fea ...

Virtual Sensor Design

Sabine Süsstrunk, Roberto Costantini

We present a virtual digital camera sensor, whose aim is to simulate a real (physical) image capturing sensor.To accomplish this task, the virtual sensor operates in two steps. First, it accepts a physical description of agiven scene and simulates the enti ...
