CMOS DETECTORS: New Techniques Recover Dynamic Range as CMOS Pixels Shrink

June 1, 2010 – As CMOS pixel sizes are aggressively scaled down to increase resolution, high-dynamic-range (HDR) techniques are required to maintain or even enhance imager performance. Anyone who has tried to take an indoor picture with a cell-phone camera of a person standing in front of a brightly lit window has experienced the limited dynamic range of CMOS image sensors.

Forza Silicon Announces High Definition CMOS Imaging Technology

Pasadena, CA – June 4, 2007 – Forza Silicon Corporation announced today the availability of its groundbreaking proprietary FORZ-HDTM CMOS imaging technology which supports frame rates up to 60 fps, proven at 33.2 Mega-pixel resolution, and features 12-bit on-chip ADCs. Read more

CMOS Integration of Capacitive, Optical, and Electrical Interconnects

We present a 90 nm test chip integrating proximity communication, optics using external lasers and photodiodes, and CML electronics on a single CMOS chip which can route data at multi-Gb/s rates through any combination of its three interconnect interfaces. Read more

CMOS lmager with Embedded Analog Early Image Processor

We present a high quality computational CMOS imager with integrated early image processing general-purpose filter. The early processor identifies in real-time areas of interest within the field of view, and reduces data volume and data-bandwidth to the external processor.  Read more

Optical Transceiver Chips Based on Co-Integration of Capacitively Coupled Proximity Interconnects and VCSELs

Combining the strengths of both proximity communication and optical communication, a new hybrid input–output (I/O) platform delivers on-chip bandwidth off-chip and over distance. We demonstrate, for the first time, a four-channel hybrid I/O interface by integrating proximity communication and vertical-cavity surface-emitting-laser-based parallel optical interconnects on the same commercial 90-nm complementary metal–oxide–semiconductor platform.

A Low Phase Noise 10 GHz Optoelectronic RF Oscillator Implemented Using CMOS Photonics

The emerging wireless communications standards at higher frequencies, especially toward 60 and 80 GHz, are challenged by the availability of cost-effective high performance oscillators. Since the bandwidth of a wireless communications system is heavily dependent on the phase noise of the local oscillator, spectral efficiency at these frequencies is limited to a fraction of that achieved in cellular, WiFi, and WiMax applications using available local oscillators (LO).

Ultra High Light Shutter Rejection Ratio Snapshot Pixel Image Sensor ASIC for Pattern Recognition

The ultra high light shutter rejection ratio snapshot pixel image sensor ASIC is designed for detecting moving objects without motion artifacts. This chip can be integrated into the fast moving pattern recognition system, such as machine vision and robot control system. Read more

A Two-Dimensional Array Imager Demonstrating Active Reset Suppression of kTC-Noise

The design and performance of a two-dimensional photodiode visible imager with a means of reducing the reset noise below the kTC limit is discussed. This active reset scheme uses feedback with an opamp per column in order to increase the gain and therefore the noise reduction over that seen for ordinary “soft” or “flushed” reset. Read more

A Smart CMOS Imager with On-Chip High-Speed Windowed Centroiding Capability

Low-power, high-speed, accurate computation of centroid from a pre-defined window in the image plane is important for a number of space-based and commercial applications. These include object tracking in robotic systems [1], autonomous navigation, image compression [2], and document copyright protection [3], as well as space guidance and navigation systems [4], and deep-space optical communication systems that require accurate and stable beam pointing for high speed data transfer [5].
