Patent number: 6933168Abstract: A method and apparatus for employing a light shield to modulate pixel color responsivity. The improved pixel includes a substrate having a photodiode with a light receiving area. A color filter array material of a first color is disposed above the substrate. The pixel has a first relative responsivity. A light shield is disposed above the substrate to modulate the pixel color responsivity. The light shield forms an aperture whose area is substantially equal to the light receiving area adjusted by a reduction factor. The reduction factor is the result of an arithmetic operation between the first relative responsivity and a second relative responsivity, associated with a second pixel of a second color.Type: GrantFiled: March 9, 2001Date of Patent: August 23, 2005Assignee: Intel CorporationInventors: Edward J.

Publication number: 20020156953Abstract: A dynamic bus inversion method transfers successive groups of bit signals across a data communications bus. The method determines the number (A) of bit signals in a current group of bit signals that will transition in state compared to the corresponding bit signals of a previous group of bit signals if the bit signals of the current group are inverted and the number (B) of bit signals in a current group of bit signals that will transition in state compared to the corresponding bit signals of a previous group of bit signals if the bit signals of the current group are not inverted. The bit signals of the current group are inverted before being transferred across the data communications bus if (A) is less than (B).Type: ApplicationFiled: February 28, 2001Publication date: October 24, 2002Inventors: Mark A.

Patent number: 6438276Abstract: What is disclosed is an apparatus for reducing row reset noise in photodiode based complementary metal oxide (CMOS) sensors. The apparatus uses at least one reference pixel for each row of pixels in a sensor array. Also, a reset noise elimination unit is provided to adjust the values received from the pixels in a particular row by an adjustment value determined from the reset values received from the reference pixels. Additionally, a method of using the apparatus is disclosed. The method has a step of providing a first reset signal to a row of pixels including the reference pixels. The method also reads out a first set of values from this row after integration. The method continues with providing a second reset signal to the row and a second set of values is read from the row. An adjustment value is calculated from the difference of the values which are read out from the reference pixels.Type: GrantFiled: September 11, 2000Date of Patent: August 20, 2002Assignee: Intel CorporationInventors: Jon M. Dhuse, Kevin M. Connolly, Mark A. Beiley

Patent number: 6433822Abstract: An architecture for self-calibration and fixed-pattern noise removal in imager chips. The column-to-column fixed pattern noise and/or pixel-to-pixel fixed pattern noise is determined through a self-calibration operation. During operation of the imager chip, when a value of a pixel is read, the read value is compensated with the fixed-pattern noise corresponding to either the column fixed pattern noise corresponding to the column having the pixel from which the value was read or to the pixel fixed pattern noise corresponding to the pixel from which the value was read.Type: GrantFiled: March 31, 1998Date of Patent: August 13, 2002Assignee: Intel CorporationInventors: Lawrence T. Clark, Mark A. Beiley, Eric J. Hoffman

Patent number: 6366320Abstract: A semiconductor circuit having an analog storage array, a sense amplifier array in which each sense amp cell generates a differential signal pair in response to receiving first and second signals from the storage array. The circuit also includes an analog multiplexer through which a selected differential signal pair is driven into a signal processing pipe. In another embodiment, the sense amp cells each include an operational amplifier (opamp) pair configured as unity-gain closed loop amplifiers for driving the differential signal pair through the analog multiplexer. To improve settling time, the opamps are designed to provide an underdamped response while loaded with the analog transmission path through the analog mux. In yet another embodiment, each sense amp cell is activated one clock cycle before it is read. This allows speedy readout while transitioning from one cell to the next.Type: GrantFiled: December 8, 1997Date of Patent: April 2, 2002Assignee: Intel CorporationInventors: Rajendran Nair, Mark A. Beiley, Morteza Afghahi
