A 1.32pw/frame∙pixel 1.2v CMOS Energy-Harvesting and Imaging (EHI) APS Imager
S. U. Ay
University of Idaho, Moscow, ID

A CMOS energy-harvesting and imaging (EHI) APS imager capable of 7.4fps video capture and 3.5μW power generation is designed, fabricated, and tested in 0.5μm CMOS. It has a 54×50 array of 21μm2 EHI pixels, 10b supply-boosted SAR-ADC and charge-pump circuits consuming 14.25μW from 1.2V resulting in a lowest power imager with 1.32pW/frame∙pixel.

A 1Mpixel, 7.5μm pixel pitch, 0.18μm CMOS image sensor with column-parallel folding-integration and cyclic ADCs has 80μVrms (1.2e-) temporal noise, 82dB dynamic range using 64 samplings in the folding-integration ADC mode. Variable gray-scale resolution of 13b through 19b is obtained by changing the number of samplings for pixel outputs.

A 256×256 pixel, 11μm pixel pitch, 0.18μm CMOS image sensor featuring pixel-level open-loop voltage amplification reaches a readout noise of 0.86e- and a dynamic range of 90dB in a single readout using a low-complexity readout circuit with 60fps. A reset method based on negative feedback allows the use of open-loop amplification while achieving PRNU of 2.5% and a peak linearity error of 1.7%.

A 1.6Mpixel, 202×205mm2 CMOS image sensor on 300mm wafer consists of pixels of 160μm pitch with a 0-to-24dB variable gain in-pixel voltage amplifier. Reset and integrated signals are simultaneously read out from the pixel through a pair of column lines. It achieves a sensitivity of 25Me-/lux∙s, random noise of 13e-rms and operates at 100fps with global synchronous shutter.

An Angle-Sensitive CMOS Imager for Single-Sensor 3D Photography
A. Wang, P. R. Gill, A. Molnar
Cornell University, Ithaca, NY

A 0.18μm 3D CMOS image sensor composed of angle-sensitive pixels captures both local incident angle and intensity. The 400×384 pixel array has a 7.5μm pitch and local diffraction gratings over each pixel. One such chip, using one lens and ambient light, enables post-capture refocus and range finding accurate to ±1.3cm at 50cm.

This paper describes a 1/13-inch VGA SoC CMOS image sensor, with a 1.75μm pixel pitch capable of outputting 30fps at full resolution. The paper focuses on the sensor core, with a size of 1.77mm2 and a power consumption of 17mW. Thel pixel architecture uses a pixel-sharing scheme that improves low-light performance.

A 1/2.33-inch 14.6Mpixel CIS is developed by employing a 1.4μm BSI pixel with a floating diffusion boosting scheme driven by coupling with additional row-wise metal-line, achieving 30% higher QE than that of an FSI sensor, 87lux for SNR=10, and no image lag, for high-sensitivity and high-speed applications.

A 16M APS-C format CMOS image sensor with 14b SAR-ADC and 8-lane LVDS output is fabricated and characterized. A 4.78μm dynamic response pixel with ring gate transistors and no STI provides 62% QE, responsivity of 49.5ke-/lux∙s, and dark current of 17e-/s @ 60°C. The readout noise floor is 2.2e- with column FPN of 0.11e- in HCG mode.

A 17.7Mpixel CMOS image sensor with a 27.5mm optical format realizes 120fps at 12b using 90nm CMOS. This sensor achieves 2.75e-rms random noise at 12b, 120fps with a maximum data rate of 34.8Gb/s. The 16 channels of scalable low-voltage signaling I/F with embedded clock operate at 2.376Gb/s each and the single-slope ADC ramp generator runs at 2.376GHz.

A 160×128 pixel array is presented detecting photons with 55ps time resolution. Each pixel comprises a counter, a time-to-digital converter, and a 10b memory, while a frame is read out every 20μs. The sensor is well suited for applications such as fast fluorescence lifetime imaging, optical rangefinding, and time-correlated single-photon counting.

  2. The IISW is the most expensive of these to attend, especially as it moves around. So regardless of where the money goes, this fact remains. Do the people involved in IISW pay full rate for the conference, travel and hotel? Well then, consider that compensation. Your case as a retired consultant is unique and businesses usually target the majority. In your unique case, perhaps you can afford to attend if you prioritize it against other living expenses including multiple residences or other investments.

  3. @ This is a fat fee to feed a bureaucracy that has forgotten why it exists.

    Civilization in a nutshell. :D

  5. Where is the disinformation? Stick to the facts. Total cost of IISW versus total cost of ISSCC. Compare total cost of IISW from your home in 2010 and total cost of ISSCC from your home in 2010. ISSCC is less expensive. You should not say that the organizers of IISW are "strictly" volunteer unless you paid in full for all of the conference, hotel and travel. Otherwise, that is disinformation. Strictly means strict. Reference to your personal situation is in no way out of bounds when you are using your personal situation in your argument: "But, when you are retired or a consultant, it is a ridiculous sum". Got to go both ways.

  6. "All the people involved do so on a strictly volunteer basis only and receive no compensation"

    @Eric, strictly means strict. If you didn't pay in full for your conference attendance, hotel fees and travel expenses, then it is not strictly volunteering. For everyone else, attending IISW is more expensive than the other 2 conferences.

    "when you are retired or a consultant, it is a ridiculous sum"

    When a personal life situation is used in the argument for what a conference should charge, then it is not out of bounds to recommend prioritizing the personal life situation. Similarly, if you don't like that, you could try to take a job and have that employer pay it for you, if this is your priority. Otherwise, there are inexpensive hotels to stay at in SF, and you can eat for less than $15/day. Attending ISSCC for you can be under $1000. Attending IISW for anyone other than yourself, is much more than $1000. If you think this is disinformation, then please state your numbers.

  7. I don't think he referred to his personal situation. I think he means anyone who is retired or a consultant.

    ISSCC registration is $895 for non member and $595 for member so members still get big benefit. But $595 still alot if paid personally.

    I dont want to stay in cheap hotel and eat $15 Macdonalds every day. So meals at IISW are high end 3x each day and good deal.

    I think IISW with 3 days all image sensor papers is a better deal than ISSCC with much less image sensor papers.

  8. My mistake for posting a personal vent and getting baited by anon's first post. Remind me not to go into politics.

  9. Let it stand: Attending ISSCC is less expensive than attending IISW. There was no disinformation here. It is not possible to access the perceived value. There are people that appreciate saving money on room and board. But even if you dine with the stars, you will still save money attending ISSCC over IISW. There is a difference as well. At ISSCC you have the choice not to spend big on room and board. The choice is made for you at IISW.

  10. Really? "Let it stand"? I think you confused my attempt to disengage with some sort of debate victory.

  11. Yes, I also agree that attending IISW is more expensive. But it has higher value to some of those that attend. ISSCC has a larger scale and is more economical.

  13. This blog is owned by an anonymous troll. A troll is someone that has a different opinion than Fossum. He hates to be wrong so now a broken link is all he can post. He got owned by the fact that he doesn't pay his own way to IISW and that ISSCC is truely less expensive to attend than IISW for everyone else.

  14. @ "This blog is owned by an anonymous troll."

    This is not true since about two weeks ago. You can see my real name and affiliation by clicking on the profile link in the top left corner.

  15. @ "Great opinion piece in the NY Times on anonymous trolls:"

    The link is incomplete with ... in the middle.

  16. Great NY Times opinion piece on anonymous trolls:

  17. Image Sensor World is a great guy. He always seems objective, anonymous or not. Probably a real asset to his company since he can see the value in work other than his own.
