Extreme Image Completion

Sabine Süsstrunk, Radhakrishna Achanta, Nikolaos Arvanitopoulos Darginis

It is challenging to complete an image whose 99 percent pixels are randomly missing. We present a solution to this extreme image completion problem. As opposed to existing techniques, our solution has a computational complexity that is linear in the number ...

The semiconductor industry, governed by the Moore's law, has achieved the almost unbelievable feat of exponentially increasing performance while lowering the costs for years. The main enabler for this achievement has been the scaling of the CMOS transistor ...

Electronic solutions for power system emulation

Guillaume Olivier Lanz

Nowadays electric power systems are subject to continuous changes and the needs in the power generation and delivery service are constantly increasing, with a higher complexity of a progressively more distributed network. Because the impact of a failure ca ...

27.3 Area-efficient 1GS/s 6b SAR ADC with charge-injection-cell-based DAC

Kyojin Choo

To support growing data bandwidths, high-speed moderate-resolution ADCs have become vital for high-speed serial links. Interleaved SAR ADCs achieve high sampling speeds and good energy efficiency. However a challenge is that these ADCs are large and theref ...

A Subthreshold Current-Sensing Sigma-Delta Modulator for Low-Voltage and Low-Power Sensor Interfaces

Alexandre Schmid, Seyed Armin Tajalli, Yusuf Leblebici, Nikola Katic

A continuous-time (CT) ΣΔ modulator for sensing and direct analog-to-digital conversion of nA-range (subthreshold) currents is presented in this work. The presented modulator uses a subthreshold technique based on subthreshold source-coupled logic cells to ...

Design and Implementation of CMOS Image Sensors for Biomedical Applications

Gözen Köklü

Since the first introduction of digital cameras, the camera market has been taking tremendous interest from many fields. This trend has even accelerated when the cost, size, and power consumption of such devices were reduced with the introduction of camera ...

We study the case of a three-user broadcast erasure channel with multiple unicast traffic sessions, where feedback from the users is fed back to the transmitter in the form of positive acknowledgment (ACK)/negative acknowledgment (NACK) messages. The capac ...

An event-detection high dynamic range CMOS image sensor

Giovanni De Micheli, Sandro Carrara, Yusuf Leblebici, Gözen Köklü

A novel CMOS image sensor is proposed to overcome the analog design limitations in Active Pixel Sensors - APS and large area overcome in Digital Pixel Sensors - DPS for use in bio-medical applications. The design includes a pixel level event generation mec ...

We consider quadratic stochastic programs with random recourse—a class of problems which is perceived to be computationally demanding. Instead of using mainstream scenario tree-based techniques, we reduce computational complexity by restricting the space o ...
