20120312963 | IMAGE SENSOR ARRANGEMENT - Each column of pixels in an image sensor array has at least two column bitlines connected to an output of each pixel. A readout input circuit includes first inputs and a second input. Each first input is connected, via a capacitance, to a comparator input node. The second input is connected via a capacitance to the same comparator input node. The first inputs receive, in parallel, an analog signal acquired from the pixels via the column bitlines. The analog signals vary during a pixel readout period and have a first level during a first calibration period and a second level during a second read period with the analog signals being constantly read onto the capacitances during both the first calibration period and the second read period. The comparator compares an average of the signals on the plurality of first inputs to the reference signal. | 12-13-2012 |

20100284701 | System And Method For Tunable Chromatic Dispersion Compensation - One embodiment sets forth a technique for measuring chromatic dispersion using reference signals within the operational range of amplifiers used to refresh data signals. One red/blue laser pair in the transmission node is used for measuring dispersion and chromatic dispersion compensation is added at each line node in the system. Since reference and data signals propagate through each amplifier, the reference signals used to measure chromatic dispersion receive the same dispersion compensation (and will have the same residual dispersion) as the data signals. Therefore, any residual dispersion in the data signals will manifest itself in downstream dispersion measurements and, thus, can be corrected. The tunable dispersion compensator in each line node may be set to compensate for the measured dispersion, thereby compensating for both the chromatic dispersion of the link connecting the current node to the prior node and any uncorrected residual dispersion from prior nodes. | 11-11-2010 |

20090109540 | Continuously tunable optical dispersion compensation synthesizers using cascaded etalons - Described is a method for designing individual stages of a multiple cascaded etalon TDC device to allow continuous thermo-optic tuning over a desired range without inducing incremental signal distortion due to uncontrolled and unpredictable dispersion of the TDC during tuning. This allows the signal to transmit without encountering periods of incremental distortion or dark spots. The method includes prior knowledge of each etalon stage, after full assembly, for spectral group delay profile as a function of temperature through modeling and/or characterization. Characterization can account for performance variations that are due to allowed manufacturing tolerances. | 04-30-2009 |
