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 ...
This paper describes a new co-processor architecture designed for CMOS sensor imaging. The co-processor unit is integrated into the image acquisition loop so as to exploit the full potential of CMOS selective access imaging technology. The processing featu ...
This work reports on the design, fabrication, and characterization of CMOS pixels for subretinal implants, which seems to be an effective way to recover visual capabilities in some types of blindness. Two possible approaches are presented for CMOS pixel im ...
Visual capabilities recovery for some kind of illness is possible through subretinal implantable device stimulation. Two possible architectures for retinal pixel are proposed, fabricated in 0.35mum CMOS and compared, including evaluation of electronic resp ...
A new fully integrated two-stage operational transconductance amplifier-capacitor (OTA-C) sine oscillator circuit configuration using a 0.5 μm CMOS digital process is described. A simple linear impedance analysis is presented to predict the amplitude and d ...
The paper presents an original analog-to-digital converter (ADC) array meeting the constraining requirements in resolution, speed, size, and low power consumption of high-performance low-cost video cameras. The converter array is based on ADC cells relying ...
