摘要： Electronic devices may include image sensors having image sensor pixels arranged in rows and columns. Pixels arranged along a column may be coupled to a common column line. Two or more column lines may by coupled to a shared analog-to-digital converter circuit. The shared analog to digital converter circuit may sample and hold reset-level or image-level voltages presented on the column line. The shared analog to digital converter circuits may pre-amplify and convert the voltages to digital signals. The shared analog-to-digital converter may simultaneously sample pixel voltages for all columns in a selected row of the pixel array. The image sensor may read the converted signals out of memory for an active row in the pixel array while simultaneously sampling and holding the voltages for the next row of the pixel array.

摘要： Many areas of biomedical research depend on the analysis of uncommon variations in individual genes or transcripts. Here we describe a method that can quantify such variation at a scale and ease heretofore unattainable. Each DNA molecule in a collection of such molecules is converted into a single particle to which thousands of copies of DNA identical in sequence to the original are bound. This population of beads then corresponds to a one-to-one representation of the starting DNA molecules. Variation within the original population of DNA molecules can then be simply assessed by counting fluorescently-labeled particles via flow cytometry. Millions of individual DNA molecules can be assessed in this fashion with standard laboratory equipment. Moreover, specific variants can be isolated by flow sorting and employed for further experimentation. This approach can be used for the identification and quantification of rare mutations as well as to study variations in gene sequences or transcripts in specific populations or tissues.

摘要： A delay line including a phase detector having two inputs and one output. The first input of the phase detector is connected to an input of the delay line. The second input of the phase detector is connected to an output of the delay line.
