Patent number: 8908072Abstract: An anti-eclipse circuit for an imaging sensor monitors the photo signal level output by a pixel to determine whether the photo signal corresponds to the pixel being operated at a saturated state. If so, there is a risk that the pixel may be susceptible to an eclipse distortion. When the pixel is detected as being operated in a saturated state, the anti-eclipse circuit pulls up the reset signal level previously stored in a sample and hold circuit to an appropriate voltage level in order to prevent an eclipse distortion from arising.Type: GrantFiled: September 9, 2013Date of Patent: December 9, 2014Assignee: Micron Technology, Inc.Inventors: Jeffrey Rysinski, Sanjayan Vinayagamoorthy

Patent number: 8482642Abstract: A pixel having an electronic shutter suitable for use in a pixel array of an imaging device includes a pinned diode and a shutter transistor. The pinned diode is utilized as a storage device while the shutter transistor controls charge transfer from the electronic shutter. The use of a pinned diode as a charge storage device for the electronic shutter permits greater charge transfer efficiency, has lower leakage (or “dark” current), and permits the resulting pixel to have a greater fill factor than pixels utilizing conventional electronic shutter circuits.Type: GrantFiled: October 31, 2011Date of Patent: July 9, 2013Assignee: Micron Technology, Inc.Inventor: Jeffrey Rysinski

Patent number: 7755684Abstract: Row drivers as a part of an image sensor device include circuitry for supplying a plurality of signals with an increased voltage and enhanced reliability to a corresponding row in a pixel array. The row driver circuitry is designed to input a signal such as row select, reset or transfer and additionally input a boosted voltage supply. The row select, reset, or transfer signal is then output with a boosted voltage that is higher than the operating voltage supply. The row driver circuit is configured so that all terminal voltages across any of the plurality of transistors within the row driver circuit are less than or equal to the operating voltage supply.Type: GrantFiled: August 29, 2006Date of Patent: July 13, 2010Assignee: Micron Technology, Inc.Inventors: Jeffrey Rysinski, Sanjayan Vinayagamoorthy
