  • In-pixel correlated double sampling with fold-over detection
    Patent number: 10027917
    Abstract: Disclosed herein are improved in-pixel correlated double sampling elements for photodetectors. The novel circuits and associated methods of the invention allow for accurate correlated double sampling while avoiding the inherent sampling errors that may occur in prior art in-pixel correlated double sampling techniques when bright or saturating signals are received.
    Type: Grant

  • Method for reading out multiple SRAM blocks with different column sizing in stitched CMOS image senor
    Patent number: 9754989
    Abstract: A stitched image sensor array on a semiconductor substrate with identical blocks that have wherein said first configuration includes enable inputs, which vary a function of the block depending on the connection to the enable inputs. The enable inputs can set an SRAM to receive different numbers of inputs.

  • Pixel with switchable high gain and high capacity modes
    Patent number: 9686483
    Abstract: Provided herein is a novel pixel circuit for image sensors such as IR ROIC image sensors. The design provides a switchable pixel with two modes. In the first mode, the pixel performs in-pixel correlated double sampling to remove reset noise. In the second mode, the pixel is configured in a high-capacity mode to avoid saturation. The pixel may be dynamically switched between modes, for example in response to lighting conditions in the scene to be imaged.

  • CTIA for IR readout integrated circuits using single ended OPAMP with in-pixel voltage regulator
    Patent number: 9219449
    Abstract: A circuit for an image sensor pixel receives photogenerated information from an image sensor, such as infrared sensor. The circuit includes a single ended operational amplifier, they can have a simple circuit such as for example 4 transistors. An additional transistor is used in the pixel to regulate the voltage that is used to drive the operational amplifier, to maintain that voltage relative to a bias level. This prevents voltage fluctuations, which would otherwise be passed to the pixel output.

  • CTIA in-pixel correlated double sampling with snapshot operation for IR readout integrated circuits
    Patent number: 9172873
    Abstract: An image sensor array that has a buffer amplifier, having a capacitor which receives photogenerated energy from a photodetector, and stores the photo generated energy in a capacitor of the buffer amplifier. A reset across the buffer amplifier is applied at a time which is sufficient to allow the amplifier to settle transiently prior to applying the clamp voltage. There is also a source follower that is enabled to operate at a time just before snapshot operation, and then turned off when the snapshot is over, to save on power.
