Morphological and Material Programability of a Hall-Effect Based Soft Tactile Sensors
Josephine Anna Eleanor Hughes, Sudong Lee
The different receptors in human skin show not only diversity in the stimuli to which they respond, but also variable sensitivity and directionality. This is often determined by their location or morphology, and can play an important role in filtering or a ...
IEEE2024Experimental Verification of the Impact of Analog CMS on CIS Readout Noise
Christian Enz, Assim Boukhayma, Raffaele Capoccia
In this article, the impact of the combination of the column-level gain and the correlated multiple sampling (CMS) on the noise of CMOS image sensor (CIS) readout chains is first analyzed. The theory is then validated experimentally with CIS readout chains ...
2020Modeling for Ultra Low Noise CMOS Image Sensors
The low-light performance of a CMOS image sensor (CIS) is one of the most important performance metrics in a camera, whether it is used in products for consumer electronics or in an image-acquisition system for machine vision or the Internet-of-Things (IoT ...
EPFL2020Design and Optimization of Low Power and Low Light Sensor
Christian Enz, Assim Boukhayma, Antonino Caizzone, Raffaele Capoccia
The current trend towards embedding more and more light sensors in portable and wearable devices is calling for higher integration and reuse of the sensor interface electronics. In many applications, the light needs to be generated locally, which becomes t ...
IEEE2020Advancing ecohydrology in the 21st century: A convergence of opportunities
Andrea Rinaldo, Gabriel George Katul, Nicolaas Cornelis van de Giesen
Nature-based solutions for water-resource challenges require advances in the science of ecohydrology. Current understanding is limited by a shortage of observations and theories that can further our capability to synthesize complex processes across scales ...
2020Full SPICE Simulation of a CMOS Active Pixel Sensor with Generalized Devices
Jean-Michel Sallese, Chiara Rossi
We present SPICE simulations of a CMOS APS pixel element consisting of the optical sensor and the circuit. The photodiode is simulated at the physics level by means of the so-called generalized devices, without any predefined compact model. Conversely, reg ...
IEEE2019High Spectral Resolution Plasmonic Color Filters with Subwavelength Dimensions
Rapid advances in image sensor technology have generated a mismatch between the small size of image sensor pixels and the achievable filter spectral resolution. This mismatch has prevented the realization of chip-based image sensors with simultaneously hig ...
